so mysteriously found by me outside the Devonshire Mansion.

I had mentioned the incidents of that night to no one, and probably not a soul on the planet guessed that the young doctor in attendance upon Alresca had possession of a little toy-weapon which formed a startling link between two existences supposed to be unconnected save in the way of business — those of Sir Cyril and Rosetta Rosa. I hesitated whether to send the dagger to Rosa, and finally decided that I would wait until I saw her again, if ever that should happen, and then do as circumstances should dictate. I oftenwondered whether the silent man with the fixed gaze, whom I had met in Oxford Street that night, had handled the dagger, or whether his presence was a mere coincidence. To my speculations I discovered no answer.
