"No, I don't," interposed the detective; "because she was able to tell me where she got the note from."

"Well, I presume she got it from me."

"Yes," replied Naball, rather surprised at this cool admission. "She received it yesterday from you."

"Oh! then, you think I'm guilty?"

"Not if you can tell me where you got the note from."

No; I was at the theatre in the morning, and found myself short of money, so I asked Mortimer for some. He gave me that five-pound note, and, as he took it, from his waistcoat pocket, I've no doubt he'll be able to recollect from whom he received it."
