"Oh," said Torry, looking keenly at the young man, "that is very easy. You may know of something in Mr. Grent's past life which may supply the motive for this crime."
"I know nothing of Mr. Grent's past life but what is good and honest," the banker answered.
"My dear sir," said the detective, "you know that when there is any trouble, one must always look for a woman. Now----"
"There is no woman in this case," interrupted Leighbourne sharply.
"Oh, pardon me, sir. Mr. Grent was killed by a woman. And a short time ago you were beginning to make some remark thereon, when you stopped and changed the subject."
Leighbourne coloured, and looked embarrassed. "I did so because I thought it impossible that Mr. Grent could have met his death at the hands of a woman. So far as I know, he was never connected with one.
"Was he not married?" asked Frank.
"Oh, yes; but of course I mean, with any other woman than his wife. Donna Inez is different."
"Donna Inez? Who is she?"
"Mrs. Grent; but as she is a Spanish-American, she prefers to be called so."
