"Why did you detest him?"

No answer. "Was it because he admired Miss Frettlby, and from all appearances, was going to marry her?"

"Well, yes," sullenly.

"And now," said Calton, impressively, "this is the whole point upon which the case turns. Why did you get into the cab with him?"

"I did not get into the cab."

"The cabman declares that you did."

"He is wrong. I never came back after I recognised Whyte."

"Then who was the man who got into the cab with Whyte?"

"I don't know."

"You have no idea?"

"Not the least."

"You are certain?"

"Yes, perfectly certain."

"He seems to have been dressed exactly like you."

"Very probably. I could name at least a dozen of my acquaintances who wear light coats over their evening dress, and soft hats."

"Do you know if Whyte had any enemies?"

"No, I don't; I know nothing about him, beyond that he came from England a short time ago with a letter of introduction to Mr. Frettlby, and had the impertinence to ask Madge to marry him."

"Where did Whyte live?"

"Down in St. Kilda, at the end of Grey Street."

"How do you know?"

"It was in the papers, and--and--" hesitatingly, "I called on him."

"Why?"

"To see if he would cease his attentions to Madge, and to tell him that she was engaged to me."

"And what did he say?"

"Laughed at me. Curse him."

"You had high words, evidently?"

Brian laughed bitterly.

"Yes, we had."

"Did anyone hear you?"

"The landlady did, I think. I saw her in the pa.s.sage as I left the house."

"The prosecution will bring her forward as a witness."

"Very likely," indifferently.

"Did you say anything likely to incriminate yourself?" Fitzgerald turned away his head.

"Yes," he answered in a low voice, "I spoke very wildly--indeed, I did not know at the time what I said."

"Did you threaten him?"

"Yes, I did. I told him I would kill him if he persisted in his plan of marrying Madge."

"Ah! if the landlady can swear that she heard you say so, it will form a strong piece of evidence against you. So far as I can see, there is only one defence, and that is an easy one--you must prove an ALIBI."

No answer.

"You say you did not come back and get into the cab?" said Calton, watching the face of the other closely.

"No, it was some one else dressed like me."

"And you have no idea who it was?"

"No, I have not."

"Then, after you left Whyte, and walked along Russell Street, where did you go?"

"I can't tell you."

"Were you intoxicated?"

"No!" indignantly

"Then you remember?"

"Yes."

"And where were you?"

"I can't tell you."
