"Then you will be in danger of the gallows."

Ferris bit his lip and shuddered. "I am innocent," he said, wonderfully calm considering his position, "but I refuse to state how I became possessed of the necklace."

[CHAPTER XIV]

A SURPRISING DISCOVERY

The next day Ferris was brought up before the magistrate on the charge of murdering Miss Gilmar. He looked pale and ill, and heard the evidence of his pawning of the necklace in absolute silence. When he was asked to defend himself he refused to utter a word; he declined even to engage a solicitor; so in the face of this conduct there was nothing for it but to commit him for trial. Ferris asked for bail, but his request being refused, he was taken back to prison, still silent. He might have been a stone image for all the information the law got out of him; and every one marvelled at his obstinacy, so dangerous to himself, so inexplicable to others.

Gebb could not understand why he acted in this way, and risked his neck in so obstinate a manner. Certainly Ferris declared himself to be innocent; but he refused to prove the truth of his words, and preserved an impenetrable silence which at once perplexed and provoked the detective. The only reason he could conjecture for the mulish behaviour of the artist was that the evidence against him was too strong for disproval, and that he knew this to be the case.

"Still he might make an effort to save himself," thought Gebb, as he sat meditating in his office, "if only to tell a lie; although I don't quite see what he could say. Mrs. Presk declared that Miss Gilmar wore her jewels on that evening, and when we found the body those jewels were gone. The principal jewel--which is a necklace--was pawned the day after the murder by Arthur Ferris, who knows Miss Wedderburn, who knew Miss Gilmar; and he refuses to state how the necklace came into his possession. If he murdered the woman his possession of the diamonds is easily accounted for: if he is innocent he must have obtained the necklace from the assassin. Therefore, if not guilty himself, he must know who is: that is plain logic."

Logic or not, the result of the argument was very unsatisfactory, and Gebb, in his own mind, was unable to decide either for or against Ferris. He had that morning informed Prain by letter about the artist's committal for trial, and asked him to call at the prison to discover if possible the reason for the strange conduct of Ferris. Also, he requested Prain to call at his office, and tell him the result of the interview. So when his meditations were interrupted by a sharp knock at the door, he quite expected to see the little solicitor enter. In place of Prain, however, he beheld the burly form of John Alder, who appeared to be different from his usual genial self.

"You are no doubt surprised to see me here, Mr. Gebb," he said, when the first greetings had passed, "but I am greatly disturbed about Ferris. He is a friend of mine, you know."

Gebb did not know about the friendship, but he was well aware that Ferris was Alder's favoured rival with Edith Wedderburn, so wondered at the tender-heartedness of the man who was distressed over the removal of an obstacle to his wooing.
