"Yes; it is strange that Sir Louis should say that Binjoy never left his side. I suppose you suspect your cousin on that account?"
"By no means. I suspect my cousin because he was himself in London on that night."
Fanks leaned back in his chair, and stared at the barrister. "What is that you say?" he cried. "Was Sir Louis in Tooley's Alley on that evening?"
"Oh, I won't go so far as that. But Louis certainly went up to London on that night. I found that out from Mrs. Jerusalem."
"And who is Mrs. Jerusalem?"
"She was the housekeeper of Sir Louis at Taxton-on-Thames. When he came in for the title he brought her here. I saw her yesterday, and she inadvertently admitted that much."
"How did you get that out of her?"
"Well, it was a fluke. She is an old servant of our family, like Mrs. Prisom. I met her while out walking, and she recognised me. I made her promise not to tell Sir Louis that I was here."
"But what excuse did you make?"
"None," said Garth, coolly. "I'll tell you a secret, Fanks. Mrs. Jerusalem likes me and hates Sir Louis. She was a foster-sister of my mother's, and she desires to see me in the place of my scientific cousin."
