CHAPTER IX.

  THE DIAMOND CLASP.

  They then left the room. Nick dispatched Patsy secretly to the Stevenshouse.

  Shortly before noon, Colonel Richmond, Horace, and Nick took a train forthe city.

  At two o'clock they entered the vault of the safe deposit company.

  It is a long room below the level of the street.

  The walls are lined with metal drawers, fastened by locks of the mostapproved pattern.

  The drawers near the floor are the largest. They are, perhaps, a footsquare, as seen when closed. Near the top of the room they are muchsmaller.

  A movable metal step-ladder stands ready for the convenience of thosewho wish to reach the boxes on the upper tiers.

  The space in the middle of the room is railed off, and there sits aguard day and night.

  "This is ours," said the colonel, advancing toward one of the largerdrawers. "I placed the diamond clasp on the very top of the pile ofjewels within. It was in a case of its own."

  Nick turned to speak to the officer in charge.

  He questioned him regarding the possibility of any person takinganything from the boxes. He asked especially about the custody of Mrs.Pond's jewels.

  "Colonel Richmond and Mrs. Pond have the two keys necessary for openingthe drawer," said the official.

  "Yes," said Colonel Richmond, speaking over his shoulder to Nick. "Itold you all about that, and I explained how the second key happened tobe in my possession instead of Mrs. Pond's."

  "True," said Nick, apologetically, "that was not what I was askingabout."

  At that moment he heard the click of the drawer as it was pulled open.

  "Here, wait for me!" he cried. "I should see everything."

  As he stepped forward Horace Richmond was just closing the little casewhich had held the diamond clasp. The colonel was turning away.

  "I am deeply disappointed," he said. "The clasp is there."

  As the colonel walked away with bowed head, Nick turned to Horace.

  The young man's face was a study. He looked as if he had seen agrave-yard full of ghosts.

  "Nick Carter," he whispered, "this is dreadful."

  "What?"

  "Hush! I had to fool him. I positively had to or he would have gonecrazy."

  He poured the words into Nick's ear in an excited whisper.

  "I made him think the clasp was in the box, but it isn't. I substitutedanother piece. The clasp is gone. What shall we do?"

  He showed Nick the box. It contained nothing. Horace had removed thepiece which he had used in the deception.

  "Good Heavens!" cried Horace. "He heard me."

  He pointed to the colonel, who stood like one who has been struck uponthe head.

  "Gone!" he cried, rushing toward them. "You deceived me!"

  Well, they searched the drawer, and the clasp certainly was not there.

  Horace explained how he had deceived the colonel by quickly puttinganother piece of jewelry into the little case when he found it empty.

  "I am clever at sleight-of-hand," said he, "or I could never have workedit. I just flashed it before your eyes, uncle, and made you think thatyou saw the clasp. Forgive me; I thought it was the best."

  "I will forgive you, Horace," said Colonel Richmond, gently; "but nowyou must believe. And you, too, Mr. Carter. Here is proof positive."

  They locked the drawer and left the vault.

  In the ante-chamber Nick turned to Horace.

  "I suppose you'll want to knock my head off when I tell you what I nowpropose to do," said the detective. "But I think it ought to be done."

  "What is it?" asked Horace.

  "I think you ought to be searched."

  "Exactly my own idea," said Horace. "It is only fair to you. Proceed."

  Nick searched him. The diamond clasp was not found. Horace certainly didnot have it.

  "I hope you're satisfied," he said to Nick. "You know perfectly wellthat I have had no opportunity to dispose of it. There wasn't muchchance in that vault."

  Nick laughed.

  "I should say not," he replied. "I'm afraid we shall have to fall backupon the theory of the colonel."

  "No theory," cried he; "but the living truth, and now proven before youboth. But let me ask, Mr. Carter, why you suspected my nephew of takingthe clasp."

  "I didn't," replied Nick promptly. "I searched him in order to removeevery possibility."

  "Surely he would have no motive for such an action."

  "None that I can see," said Nick, with perfect sincerity.

  They proceeded at once to Mrs. Stevens' house.

  It was about seven o'clock when they arrived.

  They drove up from the station, and on the way picked up Patsy.

  During the remainder of the drive, he was busy communicating with Nickin their sign language.

  "Miss Stevens is in her room," said Patsy. "She has had a doctor withher almost all the time. He refuses to say anything. I believe, upon mysoul, that I shot her last night."

  Annie O'Neil, the servant, answered the bell.

  She ushered them into the parlor, and said that Mrs. Stevens was in theroom of her daughter who was quite ill.

  Annie went upstairs to summon her mistress.

  A minute later the party below heard a scream.

  Then Mrs. Stevens appeared. She was very pale.

  In her hand she held a small object wrapped in paper.

  "I have just found this upon my daughter's pillow," she said. "I havenot removed the paper, but I know instinctively what is within. It isanother jewel."

  "I am equally sure of it," cried the colonel. "Open the package, Mrs.Stevens."

  "My hand trembles so," the lady began.

  "Don't open it now," said Nick, "wait a moment. I have a suggestion tomake. And, at any rate, we all know what is within.

  "Colonel Richmond. I suppose it is useless to plead with you further?"

  "Quite useless," said the colonel. "Millie shall have all the jewels. Iam determined to buy them of my daughter, and make the transfer atonce."

  "Well, I am beaten," said the detective. "The case has gone against me.But I will still try to help you. I wish to call your attention to thelegal aspects of this case.

  "They may surprise you, but, before, going further, I think you shouldknow them. You will not accept my authority, if I state the facts asthey are.

  "Mrs. Stevens, is it not true that you have one of the judges of theSupreme Court as your neighbor?"

  "Yes; Judge Lorrimer is our next neighbor on the south."

  "Will you kindly send your servant to his house, or perhaps--"

  He glanced at Horace.

  "All right, I'll go," said Horace. "I know the judge. But I don't seewhat you are driving at, Mr. Carter."

  "I want to persuade Colonel Richmond to get the law in the case beforehe goes further. He should consult an authority about this transferbefore he makes any more promises which may or may not be legally good."

  "I think it a good idea," said Colonel Richmond. "Horace, go over to thejudge's house."

  During the interval while he was gone very little was done. Mrs. Stevenssat holding the package, and apparently deeply moved.

  She several times declared to Colonel Richmond that she did not wish herdaughter to get the jewels in such a way, and that she was stillconvinced that human beings had planned and executed the whole strangeseries of robberies and surprises.

  "If it should prove," said Nick, "that this is a conspiracy, do you wishany arrests?"

  He turned toward the colonel as he spoke.

  "If it does," said the colonel, with a smile, "you can arrest me. Itwon't."

  "But I am serious."

  "So am I. Of course, if there had been a crime I would not shield theguilty parties, whoever they might be."

  At that moment Horace returned with Judge Lorrimer, whom he had metwalking just beyond Mrs. Stevens' grounds.

  "I have tried to explain the case to him," said Horace;
"but he says hedoesn't understand how any legal complications can arise."

  "We will try to make that clear presently," said Nick. "Mrs. Stevens,open that package. No; wait a moment. You are agitated. You should havea glass of water. Permit me to ring."

  He put his hand upon the bell-cord.

  As he did so, Mrs. Stevens opened the package. The article within rolledout upon her lap.

  It was not the diamond clasp, but an ordinary pocket-knife of largesize.

  "Why, Nick, it's yours," cried Patsy.

  "So it is," responded the detective. "But this is a diamond clasp."

  He drew the relic of the third crusade from his pocket as he spoke, andhanded it to the colonel.

  At that moment Annie O'Neil appeared at the door in answer to the bell.

  "And now," said Nick, while the others stared in wonder. "We willconsider the legal points involved.

  "Judge Lorrimer, here are the necessary blank forms. Please grant mewarrants for the arrest of Horace Richmond and Annie O'Neil for criminalconspiracy."
