But he was always kind to the boy in his own way."

  "But the sympathies of the latter were with the mother?"

  "Yes."

  "Did he say so?"

  "No."

  "The Duke, then?"

  "Good heavens, no!"

  "Then how could you know?"

  "I have had some confidential talks with Mr. James Wilder,

  his Grace's secretary. It was he who gave me the

  information about Lord Saltire's feelings."

  "I see. By the way, that last letter of the Duke's -- was it

  found in the boy's room after he was gone?"

  "No; he had taken it with him. I think, Mr. Holmes,

  it is time that we were leaving for Euston."

  "I will order a four-wheeler. In a quarter of an hour we

  shall be at your service. If you are telegraphing home,

  Mr. Huxtable, it would be well to allow the people in your

  neighbourhood to imagine that the inquiry is still going on

  in Liverpool, or wherever else that red herring led your

  pack. In the meantime I will do a little quiet work at

  your own doors, and perhaps the scent is not so cold but that

  two old hounds like Watson and myself may get a sniff of it."

  That evening found us in the cold, bracing atmosphere of

  the Peak country, in which Dr. Huxtable's famous school is

  situated. It was already dark when we reached it. A card

  was lying on the hall table, and the butler whispered

  something to his master, who turned to us with agitation

  in every heavy feature.

  "The Duke is here," said he. "The Duke and Mr. Wilder are

  in the study. Come, gentlemen, and I will introduce you."

  I was, of course, familiar with the pictures of the famous

  statesman, but the man himself was very different from his

  representation. He was a tall and stately person,

  scrupulously dressed, with a drawn, thin face, and a nose

  which was grotesquely curved and long. His complexion was

  of a dead pallor, which was more startling by contrast with

  a long, dwindling beard of vivid red, which flowed down

  over his white waistcoat, with his watch-chain gleaming

  through its fringe. Such was the stately presence who

  looked stonily at us from the centre of Dr. Huxtable's

  hearthrug. Beside him stood a very young man, whom I

  understood to be Wilder, the private secretary. He was

  small, nervous, alert, with intelligent, light-blue eyes

  and mobile features. It was he who at once, in an incisive

  and positive tone, opened the conversation.

  "I called this morning, Dr. Huxtable, too late to prevent

  you from starting for London. I learned that your object

  was to invite Mr. Sherlock Holmes to undertake the conduct

  of this case. His Grace is surprised, Dr. Huxtable, that

  you should have taken such a step without consulting him."

  "When I learned that the police had failed ----"

  "His Grace is by no means convinced that the police have

  failed."

  "But surely, Mr. Wilder ----"

  "You are well aware, Dr. Huxtable, that his Grace is

  particularly anxious to avoid all public scandal.

  He prefers to take as few people as possible into his

  confidence."

  "The matter can be easily remedied," said the brow-beaten

  doctor; "Mr. Sherlock Holmes can return to London by the

  morning train."

  "Hardly that, doctor, hardly that," said Holmes, in his

  blandest voice. "This northern air is invigorating and

  pleasant, so I propose to spend a few days upon your moors,

  and to occupy my mind as best I may. Whether I have the

  shelter of your roof or of the village inn is, of course,

  for you to decide."

  I could see that the unfortunate doctor was in the last

  stage of indecision, from which he was rescued by the deep,

  sonorous voice of the red-bearded Duke, which boomed out

  like a dinner-gong.

  "I agree with Mr. Wilder, Dr. Huxtable, that you would have

  done wisely to consult me. But since Mr. Holmes has

  already been taken into your confidence, it would indeed be

  absurd that we should not avail ourselves of his services.

  Far from going to the inn, Mr. Holmes, I should be pleased

  if you would come and stay with me at Holdernesse Hall."

  "I thank your Grace. For the purposes of my investigation

  I think that it would be wiser for me to remain at the

  scene of the mystery."

  "Just as you like, Mr. Holmes. Any information which

  Mr. Wilder or I can give you is, of course, at your disposal."

  "It will probably be necessary for me to see you at the Hall,"

  said Holmes. "I would only ask you now, sir,

  whether you have formed any explanation in your own mind

  as to the mysterious disappearance of your son?"

  "No, sir, I have not."

  "Excuse me if I allude to that which is painful to you,

  but I have no alternative. Do you think that the Duchess

  had anything to do with the matter?"

  The great Minister showed perceptible hesitation.

  "I do not think so," he said, at last.

  "The other most obvious explanation is that the child

  has been kidnapped for the purpose of levying ransom.

  You have not had any demand of the sort?"

  "No, sir."

  "One more question, your Grace. I understand that you

  wrote to your son upon the day when this incident occurred."

  "No; I wrote upon the day before."

  "Exactly. But he received it on that day?"

  "Yes."

  "Was there anything in your letter which might have

  unbalanced him or induced him to take such a step?"

  "No, sir, certainly not."

  "Did you post that letter yourself?"

  The nobleman's reply was interrupted by his secretary,

  who broke in with some heat.

  "His Grace is not in the habit of posting letters himself,"

  said he. "This letter was laid with others upon the study

  table, and I myself put them in the post-bag."

  "You are sure this one was among them?"

  "Yes; I observed it."

  "How many letters did your Grace write that day?"

  "Twenty or thirty. I have a large correspondence.

  But surely this is somewhat irrelevant?"

  "Not entirely," said Holmes.

  "For my own part," the Duke continued, "I have advised the

  police to turn their attention to the South of France.

  I have already said that I do not believe that the Duchess

  would encourage so monstrous an action, but the lad had the

  most wrong-headed opinions, and it is possible that he may

  have fled to her, aided and abetted by this German.

  I think, Dr. Huxtable, that we will now return to the Hall."

  I could see that there were other questions which Holmes

  would have wished to put; but the nobleman's abrupt manner

  showed that the interview was at an end. It was evident

  that to his intensely aristocratic nature this discussion

  of his intimate family affairs with a stranger was most

  abhorrent, and that he feared lest every fresh question

  would throw a fiercer light into the discreetly shadowed
r />   corners of his ducal history.

  When the nobleman and his secretary had left, my friend

  flung himself at once with characteristic eagerness into

  the investigation.

  The boy's chamber was carefully examined, and yielded

  nothing save the absolute conviction that it was only

  through the window that he could have escaped.

  The German master's room and effects gave no further clue.

  In his case a trailer of ivy had given way under his weight,

  and we saw by the light of a lantern the mark on the lawn

  where his heels had come down. That one dint in the short

  green grass was the only material witness left of this

  inexplicable nocturnal flight.

  Sherlock Holmes left the house alone, and only returned

  after eleven. He had obtained a large ordnance map of the

  neighbourhood, and this he brought into my room, where he

  laid it out on the bed, and, having balanced the lamp in

  the middle of it, he began to smoke over it, and

  occasionally to point out objects of interest with the

  reeking amber of his pipe.

  "This case grows upon me, Watson," said he. "There are

  decidedly some points of interest in connection with it.

  In this early stage I want you to realize those

  geographical features which may have a good deal to do with

  our investigation.

  {GRAPHIC}

  "Look at this map. This dark square is the Priory School.

  I'll put a pin in it. Now, this line is the main road.

  You see that it runs east and west past the school, and you

  see also that there is no side road for a mile either way.

  If these two folk passed away by road it was _this_ road."

  "Exactly."

  "By a singular and happy chance we are able to some extent

  to check what passed along this road during the night in

  question. At this point, where my pipe is now resting, a

  country constable was on duty from twelve to six. It is,

  as you perceive, the first cross road on the east side.

  This man declares that he was not absent from his post for

  an instant, and he is positive that neither boy nor man

  could have gone that way unseen. I have spoken with this

  policeman to-night, and he appears to me to be a perfectly

  reliable person. That blocks this end. We have now to

  deal with the other. There is an inn here, the Red Bull,

  the landlady of which was ill. She had sent to Mackleton

  for a doctor, but he did not arrive until morning, being

  absent at another case. The people at the inn were alert

  all night, awaiting his coming, and one or other of them

  seems to have continually had an eye upon the road. They

  declare that no one passed. If their evidence is good,

  then we are fortunate enough to be able to block the west,

  and also to be able to say that the fugitives did _not_ use

  the road at all."

  "But the bicycle?" I objected.

  "Quite so. We will come to the bicycle presently.

  To continue our reasoning: if these people did not go by the

  road, they must have traversed the country to the north of

  the house or to the south of the house. That is certain.

  Let us weigh the one against the other. On the south of

  the house is, as you perceive, a large district of arable

  land, cut up into small fields, with stone walls between

  them. There, I admit that a bicycle is impossible. We can

  dismiss the idea. We turn to the country on the north.

  Here there lies a grove of trees, marked as the 'Ragged

  Shaw,' and on the farther side stretches a great rolling

  moor, Lower Gill Moor, extending for ten miles and sloping

  gradually upwards. Here, at one side of this wilderness,

  is Holdernesse Hall, ten miles by road, but only six across

  the moor. It is a peculiarly desolate plain. A few moor

  farmers have small holdings, where they rear sheep and

  cattle. Except these, the plover and the curlew are the only

  inhabitants until you come to the Chesterfield high road.

  There is a church there, you see, a few cottages, and an inn.

  Beyond that the hills become precipitous.

  Surely it is here to the north that our quest must lie."

  "But the bicycle?" I persisted.

  "Well, well!" said Holmes, impatiently. "A good cyclist

  does not need a high road. The moor is intersected with

  paths and the moon was at the full. Halloa! what is this?"

  There was an agitated knock at the door, and an instant

  afterwards Dr. Huxtable was in the room. In his hand he

  held a blue cricket-cap, with a white chevron on the peak.

  "At last we have a clue!" he cried. "Thank Heaven! at last

  we are on the dear boy's track! It is his cap."

  "Where was it found?"

  "In the van of the gipsies who camped on the moor.

  They left on Tuesday. To-day the police traced them down

  and examined their caravan. This was found."

  "How do they account for it?"

  "They shuffled and lied -- said that they found it on the

  moor on Tuesday morning. They know where he is, the

  rascals! Thank goodness, they are all safe under lock and

  key. Either the fear of the law or the Duke's purse will

  certainly get out of them all that they know."

  "So far, so good," said Holmes, when the doctor had at last

  left the room. "It at least bears out the theory that it

  is on the side of the Lower Gill Moor that we must hope for

  results. The police have really done nothing locally, save

  the arrest of these gipsies. Look here, Watson! There is

  a watercourse across the moor. You see it marked here in

  the map. In some parts it widens into a morass. This is

  particularly so in the region between Holdernesse Hall and

  the school. It is vain to look elsewhere for tracks in

  this dry weather; but at _that_ point there is certainly a

  chance of some record being left. I will call you early

  to-morrow morning, and you and I will try if we can throw

  some little light upon the mystery."

  The day was just breaking when I woke to find the long,

  thin form of Holmes by my bedside. He was fully dressed,

  and had apparently already been out.

  "I have done the lawn and the bicycle shed," said he.

  "I have also had a ramble through the Ragged Shaw.

  Now, Watson, there is cocoa ready in the next room.

  I must beg you to hurry, for we have a great day before us."

  His eyes shone, and his cheek was flushed with the

  exhilaration of the master workman who sees his work lie

  ready before him. A very different Holmes, this active,

  alert man, from the introspective and pallid dreamer of

  Baker Street. I felt, as I looked upon that supple figure,

  alive with nervous energy, that it was indeed a strenuous

  day that awaited us.

  And yet it opened in the blackest disappointment.

  With high hopes we struck across the peaty, russet moor,

  intersected with a thousand sheep paths, until we came to

  the broad, light-green belt w
hich marked the morass between

  us and Holdernesse. Certainly, if the lad had gone

  homewards, he must have passed this, and he could not pass

  it without leaving his traces. But no sign of him or the

  German could be seen. With a darkening face my friend

  strode along the margin, eagerly observant of every muddy

  stain upon the mossy surface. Sheep-marks there were in

  profusion, and at one place, some miles down, cows had left

  their tracks. Nothing more.

  "Check number one," said Holmes, looking gloomily over the

  rolling expanse of the moor. "There is another morass down

  yonder and a narrow neck between. Halloa! halloa! halloa!

  what have we here?"

  We had come on a small black ribbon of pathway.

  In the middle of it, clearly marked on the sodden soil,

  was the track of a bicycle.

  "Hurrah!" I cried. "We have it."

  But Holmes was shaking his head, and his face was puzzled

  and expectant rather than joyous.

  "A bicycle certainly, but not _the_ bicycle," said he.

  "I am familiar with forty-two different impressions left

  by tyres. This, as you perceive, is a Dunlop, with a patch

  upon the outer cover. Heidegger's tyres were Palmer's,

  leaving longitudinal stripes. Aveling, the mathematical

  master, was sure upon the point. Therefore, it is not

  Heidegger's track."

  "The boy's, then?"

  "Possibly, if we could prove a bicycle to have been in his

  possession. But this we have utterly failed to do.

  This track, as you perceive, was made by a rider who was

  going from the direction of the school."

  "Or towards it?"

  "No, no, my dear Watson. The more deeply sunk impression

  is, of course, the hind wheel, upon which the weight rests.

  You perceive several places where it has passed across and

  obliterated the more shallow mark of the front one. It was

  undoubtedly heading away from the school. It may or may

  not be connected with our inquiry, but we will follow it

  backwards before we go any farther."

  We did so, and at the end of a few hundred yards lost the

  tracks as we emerged from the boggy portion of the moor.

  Following the path backwards, we picked out another spot,

  where a spring trickled across it. Here, once again, was

  the mark of the bicycle, though nearly obliterated by the

  hoofs of cows. After that there was no sign, but the path

  ran right on into Ragged Shaw, the wood which backed on to

  the school. From this wood the cycle must have emerged.

  Holmes sat down on a boulder and rested his chin in his

  hands. I had smoked two cigarettes before he moved.

  "Well, well," said he, at last. "It is, of course,

  possible that a cunning man might change the tyre of his

  bicycle in order to leave unfamiliar tracks. A criminal

  who was capable of such a thought is a man whom I should be

  proud to do business with. We will leave this question

  undecided and hark back to our morass again, for we have

  left a good deal unexplored."

  We continued our systematic survey of the edge of the

  sodden portion of the moor, and soon our perseverance was

  gloriously rewarded. Right across the lower part of the

  bog lay a miry path. Holmes gave a cry of delight as he

  approached it. An impression like a fine bundle of telegraph

  wires ran down the centre of it. It was the Palmer tyre.

  "Here is Herr Heidegger, sure enough!" cried Holmes, exultantly.

  "My reasoning seems to have been pretty sound, Watson."

  "I congratulate you."

  "But we have a long way still to go. Kindly walk clear of

  the path. Now let us follow the trail. I fear that it

  will not lead very far."

  We found, however, as we advanced that this portion of the

  moor is intersected with soft patches, and, though we

  frequently lost sight of the track, we always succeeded in

  picking it up once more.

  "Do you observe," said Holmes, "that the rider is now
