"She is old enough to be my mother, sir," I whispered; "and this time, at
   any rare, she has told you the truth."
   Hardly a word passed between us on our way through the streets and over
   the bridge. Minna was sad and silent, thinking of Fritz; and whatever her
   mother might have to say to me, was evidently to be said in private.
   Arrived at the lodgings, Madame Fontaine requested me to wait for her in
   the shabby little sitting-room, and graciously gave me permission to
   smoke. "Say good night to David," she continued, turning to her daughter.
   "Your poor little heart is heavy to-night, and mamma means to put you to
   bed as if you were a child again. Ah! me, if those days could only come
   back!"
   After a short absence the widow returned to me, with a composed manner
   and a quiet smile. The meeting with Mr. Keller seemed to have been
   completely dismissed from her thoughts, in the brief interval since I had
   seen her last.
   "We often hear of parents improving their children," she said. "It is my
   belief that the children quite as often improve the parents. I have had
   some happy minutes with Minna--and (would you believe it?) I am already
   disposed to forgive Mr. Keller's brutality, and to write to him in a tone
   of moderation, which must surely have its effect. All Minna's doing--and
   my sweet girl doesn't in the least suspect it herself! If you ever have
   children of your own, David, you will understand me and feel for me. In
   the meantime, I must not detain you by idle talk--I must say plainly what
   I want of you." She opened her writing-desk and took up a pen. "If I
   write to Mr. Keller under your own eye, do you object to take charge of
   my letter?"
   I hesitated how to answer. To say the least of it, her request
   embarrassed me.
   "I don't expect you to give it to Mr. Keller personally," she explained.
   "It is of very serious importance to me" (she laid a marked emphasis on
   those words) "to be quite sure that my letter has reached him, and that
   he has really had the opportunity of reading it. If you will only place
   it on his desk in the office, with your own hand, that is all I ask you
   to do. For Minna's sake, mind; not for mine!"
   For Minna's sake, I consented. She rose directly, and signed to me to
   take her place at the desk.
   "It will save time," she said, "if you write the rough draft of the
   letter from my dictation. I am accustomed to dictate my letters, with
   Minna for secretary. Of course, you shall see the fair copy before I seal
   it."
   She began to walk up and down the little room, with her hands crossed
   behind her in the attitude made famous by the great Napoleon. After a
   minute of consideration, she dictated the draft as follows:
   "Sir,--I am well aware that scandalous reports at Wurzburg have
   prejudiced you against me. Those reports, so far as I know, may be summed
   up under three heads.
   "(First.) That my husband died in debt through my extravagance.
   "(Second.) That my respectable neighbors refuse to associate with me.
   "(Third.) That I entrapped your son Fritz into asking for my daughter's
   hand in marriage, because I knew his father to be a rich man.
   "To the first calumny I reply, that the debts are due to expensive
   chemical experiments in which my late husband engaged, and that I have
   satisfied the creditors to the last farthing. Grant me an audience, and I
   will refer you to the creditors themselves.
   "To the second calumny I reply, that I received invitations, on my
   arrival in Wurzburg after my marriage, from every lady of distinguished
   social position in the town. After experience of the society thus offered
   to me, I own to having courteously declined subsequent invitations, and
   having devoted myself in retirement to my husband, to my infant child,
   and to such studies in literature and art as I had time to pursue. Gossip
   and scandal, with an eternal accompaniment of knitting, are not to my
   taste; and, while I strictly attend to domestic duties, I do not consider
   them as constituting, in connection with tea-drinking, the one great
   interest of a woman's life. I plead guilty to having been foolish enough
   to openly acknowledge these sentiments, and to having made bitter enemies
   everywhere as the necessary consequence. If this plain defense of myself
   fails to satisfy you, grant me an audience, and I will answer your
   questions, whatever they may be.
   "To the third calumny, I reply, that if you had been a Prince instead of
   a merchant, I would still have done everything in my power to keep your
   son away from my daughter--for this simple reason, that the idea of
   parting with her to any man fills me with grief and dismay. I only
   yielded to the marriage engagement, when the conviction was forced upon
   me that my poor child's happiness depended on her union with your son. It
   is this consideration alone which induces me to write to you, and to
   humiliate myself by pleading for a hearing. As for the question of money,
   if through some unexpected misfortune you became a bankrupt to-morrow, I
   would entreat you to consent to the marriage exactly as I entreat you
   now. Poverty has no terrors for me while I have health to work. But I
   cannot face the idea of my child's life being blighted, because you
   choose to believe the slanders that are spoken of her mother. For the
   third time I ask you to grant me an audience, and to hear me in my own
   defense."
   There she paused, and looked over my shoulder.
   "I think that is enough," she said. "Do you see anything objectionable in
   my letter?"
   How could I object to the letter? From beginning to end, it was strongly,
   and yet moderately, expressed. I resigned my place at the desk, and the
   widow wrote the fair copy, with her own hand. She made no change
   whatever, except by adding these ominous lines as a postscript:
   "I implore you not to drive me to despair. A mother who is pleading for
   her child's life--it is nothing less, in this case--is a woman who surely
   asserts a sacred claim. Let no wise man deny it."
   "Do you think it quite discreet," I ventured to ask, "to add those
   words?"
   She looked at me with a moment's furtive scrutiny, and only answered
   after she had sealed the letter, and placed it in my hands.
   "I have my reasons," she replied. "Let the words remain."
   Returning to the house at rather a late hour for Frankfort, I was
   surprised to find Mr. Keller waiting to see me.
   "I have had a talk with my partner," he said. "It has left (for the time
   only, I hope), a painful impression on both sides--and I must ask you to
   do me a service, in the place of Mr. Engelman--who has an engagement
   to-morrow, which prevents him from leaving Frankfort."
   His tone indicated plainly enough that the "engagement" was with Madame
   Fontaine. Hard words must have passed between the two old friends on the
   subject of the widow. Even Mr. Engelman's placid temper had, no doubt,
   resented Mr. Keller's conduct at the meeting in the hall.
   "The service I ask of you," he resumed, "will be easily rendered. The
   proprietor of a commercial e 
					     					 			stablishment at Hanau is desirous of entering
   into business-relations with us, and has sent references to respectable
   persons in the town and neighborhood, which it is necessary to verify. We
   are so busy in the office that it is impossible for me to leave Frankfort
   myself, or to employ our clerks on this errand. I have drawn out the
   necessary instructions--and Hanau, as you are aware, is within an easy
   distance of Frankfort. Have you any objection to be the representative of
   the house in this matter?"
   It is needless to say that I was gratified by the confidence that had
   been placed in me, and eager to show that I really deserved it. We
   arranged that I should leave Frankfort by the earliest conveyance the
   next morning.
   On our way upstairs to our bed-chambers, Mr. Keller detained me for a
   moment more.
   "I have no claim to control you in the choice of your friends," he said;
   "but I am old enough to give you a word of advice. Don't associate
   yourself too readily, David, with the woman whom I found here to-night."
   He shook hands cordially, and left me. I thought of Madame Fontaine's
   letter in my pocket, and felt a strong conviction that he would persist
   in his refusal to read it.
   The servants were the only persons stirring in the house, when I rose the
   next morning. Unobserved by anyone, I placed the letter on the desk in
   Mr. Keller's private room. That done, I started on my journey to Hanau.
   CHAPTER XIV
   Thanks to the instructions confided to me, my errand presented no
   difficulties. There were certain persons to whom I was introduced, and
   certain information to be derived from them, which it was my duty to
   submit to Mr. Keller on my return. Fidelity was required of me, and
   discretion was required of me--and that was all.
   At the close of my day's work, the hospitable merchant, whose references
   I had been engaged in verifying, refused to permit me to return to the
   hotel. His dinner-hour had been put off expressly to suit my convenience.
   "You will only meet the members of my family," he said, "and a cousin of
   my wife's who is here with her daughter, on a visit to us--Frau Meyer, of
   Wurzburg."
   I accepted the invitation, feeling privately an Englishman's reluctance
   to confronting an assembly of strangers, and anticipating nothing
   remarkable in reference to Frau Meyer, although she did come from
   Wurzburg. Even when I was presented to the ladies in due form, as "the
   honored representative of Mr. Keller, of Frankfort," I was too stupid, or
   too much absorbed in the business on which I had been engaged, to be much
   struck by the sudden interest with which Frau Meyer regarded me. She was
   a fat florid old lady, who looked coarsely clever and resolute; and she
   had a daughter who promised to resemble her but too faithfully, in due
   course of time. It was a relief to me, at dinner, to find myself placed
   between the merchant's wife and her eldest son. They were far more
   attractive neighbors at table, to my thinking, than Frau Meyer.
   Dinner being over, we withdrew to another room to take our coffee. The
   merchant and his son, both ardent musicians in their leisure hours,
   played a sonata for pianoforte and violin. I was at the opposite
   extremity of the room, looking at some fine proof impressions of prints
   from the old masters, when a voice at my side startled me by an
   unexpected question.
   "May I ask, sir, if you are acquainted with Mr. Keller's son?"
   I looked round, and discovered Frau Meyer.
   "Have you seen him lately?" she proceeded, when I had acknowledged that I
   was acquainted with Fritz. "And can you tell me where he is now?"
   I answered both these questions. Frau Meyer looked thoroughly well
   satisfied with me. "Let us have a little talk," she said, and seated
   herself, and signed to me to take a chair near her.
   "I feel a true interest in Fritz," she resumed, lowering her voice so as
   not to be heard by the musicians at the other end of the room. "Until
   to-day, I have heard nothing of him since he left Wurzburg. I like to
   talk about him--he once did me a kindness a long time since. I suppose
   you are in his confidence? Has he told you why his father sent him away
   from the University?"
   My reply to this was, I am afraid, rather absently given. The truth is,
   my mind was running on some earlier words which had dropped from the old
   lady's lips. "He once did me a kindness a long time since." When had I
   last heard that commonplace phrase? and why did I remember it so readily
   when I now heard it again?
   "Ah, his father did a wise thing in separating him from that woman and
   her daughter!" Frau Meyer went on. "Madame Fontaine deliberately
   entrapped the poor boy into the engagement. But perhaps you are a friend
   of hers? In that case, I retract and apologize."
   "Quite needless," I said.
   "You are _not_ a friend of Madame Fontaine?" she persisted.
   This cool attempt to force an answer from me failed in its object. It was
   like being cross-examined in a court of law; and, in our common English
   phrase, "it set my back up." In the strict sense of the word, Madame
   Fontaine might be termed an acquaintance, but certainly not a friend, of
   mine. For once, I took the prudent course, and said, No.
   Frau Meyer's expansive bosom emitted a hearty sigh of relief. "Ah!" she
   said, "now I can talk freely--in Fritz's interest, mind. You are a young
   man like himself, he will be disposed to listen to you. Do all you can to
   back his father's influence, and cure him of his infatuation. I tell you
   plainly, his marriage would be his ruin!"
   "You speak very strongly, madam. Do you object to the young lady?"
   "Not I; a harmless insignificant creature--nothing more and nothing less.
   It's her vile mother that I object to."
   "As I have heard, Frau Meyer, there are two sides to that question. Fritz
   is persuaded that Madame Fontaine is an injured woman. He assures me, for
   instance, that she is the fondest of mothers."
   "Bah! What does _that_ amount to? It's as much a part of a woman's nature
   to take to her child when she has got one, as it is to take to her dinner
   when she is hungry. A fond mother? What stuff! Why, a cat is a fond
   mother!--What's the matter?"
   _A cat is a fond mother._ Another familiar phrase--and this time a phrase
   remarkable enough to lead my memory back in the right direction. In an
   instant I recollected the anonymous letter to Fritz. In an instant I felt
   the conviction that Frau Meyer, in her eagerness to persuade me, had
   unconsciously repeated two of the phrases which she had already used, in
   her eagerness to persuade Fritz. No wonder I started in my chair, when I
   felt that I was face to face with the writer of the anonymous letter!
   I made some excuse--I forget what--and hastened to resume the
   conversation. The opportunity of making discoveries which might be
   invaluable to Fritz (to say nothing of good Mr. Engelman) was not an
   opportunity to be neglected. I persisted in quoting Fritz's authority; I
   repeated his assertion relative to the love of scandal at Wurzburg, and
 
					     					 			
   the envy of Madame Fontaine's superior attractions felt among the ladies.
   Frau Meyer laughed disdainfully.
   "Poor Fritz!" she said. "An excellent disposition--but so easily
   persuaded, so much too amiable. Our being all envious of Widow Fontaine
   is too ridiculous. It is a mere waste of time to notice such nonsense.
   Wait a little, Mr. David, and you will see. If you and Mr. Keller can
   only keep Fritz out of the widow's way for a few months longer, his eyes
   will be opened in spite of himself. He may yet come back to us with a
   free heart, and he may choose his future wife more wisely next time."
   As she said this her eyes wandered away to her daughter, at the other end
   of the room. Unless her face betrayed her, she had evidently planned, at
   some past time, to possess herself of Fritz as a son-in-law, and she had
   not resigned the hope of securing him yet. Madame Fontaine might be a
   deceitful and dangerous woman. But what sort of witness against her was
   this abusive old lady, the unscrupulous writer of an anonymous letter?
   "You prophesy very confidently about what is to come in the future," I
   ventured to say.
   Frau Meyer's red face turned a shade redder. "Does that mean that you
   don't believe me?" she asked.
   "Certainly not, madam. It only means that you speak severely of Doctor
   Fontaine's widow--without mentioning any facts that justify you."
   "Oh! you want facts, do you? I'll soon show you whether I know what I am
   talking about or not. Has Fritz mentioned that among Madame Fontaine's
   other virtues, she has paid her debts? I'll tell you how she has paid
   them--as an example, young gentleman, that I am not talking at random.
   Your admirable widow, sir, is great at fascinating old men; they are
   always falling in love with her, the idiots! A certain old man at
   Wurzburg--close on eighty, mind--was one of her victims. I had a letter
   this morning which tells me that he was found dead in his bed, two days
   since, and that his nephew is the sole heir to all that he leaves behind
   him. Examination of his papers has shown that _he_ paid the widow's
   creditors, and that he took a promissory note from her--ha! ha! ha!--a
   promissory note from a woman without a farthing!--in payment of the sum
   that he had advanced. The poor old man would, no doubt, have destroyed
   the note if he had known that his end was so near. His sudden death has
   transferred it to the hands of his heir. In money-matters, the nephew is
   reported to be one of the hardest men living. When that note falls due,
   he will present it for payment. I don't know where Madame Fontaine is
   now. No matter! Sooner or later, she is sure to hear of what has
   happened--and she must find the money, or see the inside of a debtor's
   prison. Those are the facts that I had in my mind, Mr. David, when I
   spoke of events opening Fritz's eyes to the truth."
   I submitted with all possible humility to the lady's triumph over me. My
   thoughts were with Minna. What a prospect for the innocent, affectionate
   girl! Assuming the statement that I had just heard to be true, there was
   surely a chance that Madame Fontaine (with time before her) might find
   the money. I put this view of the case to Frau Meyer.
   "If I didn't know Mr. Keller to be a thoroughly resolute man," she
   answered, "I should say she might find the money too. She has only to
   succeed in marrying her daughter to Fritz, and Mr. Keller would be
   obliged to pay the money for the sake of the family credit. But he is one
   of the few men whom she can't twist round her finger. If you ever fall in
   with her, take care of yourself. She may find your influence with Fritz
   an obstacle in her way--and she may give you reason to remember that the
   mystery of her husband's lost chest of poisons is not cleared up yet. It
