Could Ali be a Peruvian Indian and not a Hindu? Was he the accomplice of the mysterious Englishman named Cane—the man suspected of causing the death of Sir Digby Kemsley?

What this girl was revealing was certainly amazing.

"You are quite sure that this man she called Digby left the neighbourhood last Sunday?" I asked her.

"Quite. I overheard him speaking with the mistress late on Saturday night. He said, 'By this time to-morrow I shall be back in Brussels.' And I know he went there, for next day I posted a letter to Brussels."

"To him?" I cried. "What was the address?"

"The name was Bryant, and it was addressed Poste Restante, Brussels. I remember it, because I carefully made a note of it, as the whole affair seemed so extraordinary."

"But this man she called Digby. Was he well-dressed?" I inquired.

"Oh, no—not at all. He seemed poor and shabby. He only had with him a little handbag, but I believe he came from a considerable distance, probably from abroad, expressly to see her."

"Then you think he is in Brussels now?"

"Well, I posted the letter on Monday night. To-day is Wednesday," she said.
