"You say he was engaged in service in London?"

"Yes, at a restaurant in Oxford Street, I believe. I met him accidentally in Pall Mall one evening, and he told me so."

"You don't know the name of the restaurant?"

"He did tell me, but unfortunately I have forgotten."

The detective drew a deep breath of regret.

"Someone who waited for him on the edge of that wood stepped out and killed him—that's evident," he said.

"Without a doubt."

"And my belief is that it was an Italian. There were two foreigners who slept at a common lodging-house two nights ago and went on tramp towards Glasgow. We have telegraphed after them, and hope we shall find them. Scotsmen or Englishmen never use a knife of that pattern."

With his latter remark I entirely coincided. In my own mind that was the strongest argument in favor of Leithcourt's innocence. That the tenant of Rannoch had kept that secret tryst in daily patience I knew from my own observations, yet to me it scarcely seemed feasible that he would use a weapon so peculiarly Italian and yet so terribly deadly.

And then when I reflected further, recollecting that the body I had discovered was that of a woman and not a man, I stood staggered and bewildered by the utterly inexplicable enigma.
