did you spring from?"

"From the cab, of course," answered Calton, with a laugh.

"A kind of DEUS EX MACHINA," replied Rolleston, attempting a bad pun.

"Exactly," said Calton. "Look here, Rolleston, do you remember the
night of Whyte's murder--you met Fitzgerald at the Railway Station."

"In the train," corrected Felix.

"Well, well, no matter, you came up with him to the Club."

"Yes, and left him there."

"Did you notice if he received any message while he was with you?"

"Any message?" repeated Felix. "No, he did not; we were talking
together the whole time, and he spoke to no one but me."

"Was he in good spirits?"

"Excellent, made me laugh awfully--but why all this thusness?"

"Oh, nothing," answered Calton, getting back into the cab. "I wanted a
little information from you; I'll explain next time I see you--
Good-bye!"

"But I say," began Felix, but the cab had already rattled away,
so Mr. Rolleston turned angrily away.
