“Under the name of——?”

“Janet Vandemeyer. I understood her to be a niece of Mrs. Vandemeyer’s.”

“And she came to you?”

“As far as I can remember in June or July of 1915.”

“Was she a mental case?”

“She is perfectly sane, if that is what you mean. I understood from Mrs. Vandemeyer that the girl had been with her on the Lusitania when that ill-fated ship was sunk, and had suffered a severe shock in consequence.”

“We’re on the right track, I think?” Sir James looked round.

“As I said before, I’m a mutt!” returned Julius.

The doctor looked at them all curiously.
