delay of communicating with my friend in England." Each was flattering himself on his discretion, the whole catechism having been gone through without the question on either side, "Is the person a man or a woman?" Eventually we parted with the understanding that I should return later if, after looking at the Alhambra from the outside, I fancied it as much as I expected to do. And then I was to bring the photograph with me. So far so good. But the next steps were not so simple. I stopped my taxi at the corner (not to advertise myself with unnecessary noise) and limped the short distance which Perry Callender-Graham and his brother Ned must have travelled on the secret errands that led them to their death. The Alhambra was neither as picturesque nor as imposing as its name suggested. It was just a substantial brick building, six or seven storeys in height, with facings of light-coloured stone, and large, cheerful windows. Luckily for my lame leg, the entrance was but a step above the street level. As I arrived the door was opened by a chocolate-brown negro in chocolate-brown livery.

Fortunately, however, someone rang for the lift and the porter shot down again, directing me to the right. The instant he was out of sight I turned to the left, and, with the police key in my hand, I stood before the door of T. Paulling. My blood leaped through my veins, and the hand that tried the key in the lock shook with the rush of it. I heard its pounding in my ears, and through the murmurous sound the question whispered, "What if the key won't fit? Down goes the
