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. He helped a smart nurse to pass out with a baby in a white and gold chariot, and while he was thus engaged I hobbled into the hall. A hasty glance at a name board on the wall opposite gave me the list of occupants and the floor on which each tenant lived. Evidently there were two flats to each storey. T. Paulling had an apartment on the third, so also had G. Emmett. I had to risk something, and so when the brown hall-porter turned to me (which he did with embarrassing swiftness) I risked inquiring for Mr. Emmett. I believed, I added, that he was expecting me.
"That's all right, sir. He's in," was the welcome reply, with a compassionate grin at the crutches which guaranteed the harmlessness of an unknown visitor. "I'll take you in the elevator."
Up we shot to the third floor, where I feared that my conductor might insist on guiding me to the door of Mr. Emmett. 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 whole theory. You'll have to confess yourself a fool to Roger Odell."
As I blundered at the lock in haste and fear that someone might pass, or that this might be one of T. Paulling's rare days at the flat, I was aghast at my late self-confidence. Face to face with the test, it seemed impossible that my-boast to Odell and Carr could succeed. I felt callow and stupid, altogether incompetent. The key seemed too large and the wrong shape, which meant that the mystery of the brothers' death was closed to me, like the door. A voice not far off made my nerves jump, and—the key slipped into the lock! From somewhere above or below came the sound of voices, but I could not be seen from the lift. Almost before I knew what I was doing or what had happened, I was on the other side of the door, in a dark and stuffy vestibule.
The sound of voices was suddenly stilled. It was as if with a single step I had won my way into another world. I drew a long breath of relief after the strain, for the silence and darkness said that the tenant was not at home, and I might hope to have the flat to myself.
I groped for an electric switch, touched it, and flooded the vestibule with light. It was small, with nothing to distinguish it from any other vestibule of any other well-furnished flat. Beyond led a narrow corridor which, when lit, showed me several doors. I opened the nearest, switched on another light, and found myself on the threshold of a moderate-sized sitting-room or study, with bookshelves ranged along one of the walls. The window was so heavily curtained that I had no fear of the sudden illumination being noticed from the street. The air was heavy and smelled of moth powder. The mahogany table in the centre of the room and the desk under the window were coated with thin films of dust, but everything was stiffly in order: no books lying about, no woman's work, no trace of cigarette ash, dropped glove, nor pile of newspapers with a tell-tale date.
