“Of course I know the servants belonging to every household on the block,” the gray-haired watchman was saying in a slightly lofty tone. “Mr. Orbit has none with the initials you mention, Inspector, and no house guests at present or I should have been notified. It’s my business, and the day man’s, to know everybody who comes and goes through the gates.”
“You see, Mac?” Dennis nudged his companion. “’Tis worse than a jail!”
But McCarty paid no heed. He was eyeing the house fronts as they passed with a gaze of critical absorption, giving quick glances at the occasional lighted windows of those across the way, but the latter were all discreetly curtained, and the first two houses on the south side were utterly dark. The third—Number Six—was a rococo affair of some pinkish stone, bristling with tiny pointed turrets and unexpected balconies. Here a brilliant light shone from the upper floors, but the next house—Number Four—although small in contrast to the mansions across the street, gave an impression of size in its stately lines of snowy marble, broken only by the windows with dark, graceful vines trailing from the boxes on each sill.
It appeared to be attached to the farther house by a conservatory of some sort, but there was no time to explore further, for the watchman had halted and Inspector Druet mounted the steps and rang the bell. McCarty followed with Dennis at his heels. As they paused, waiting, the soft but deeply resonant tones of an organ came to their ears from behind the windows to their right, from which emanated a subdued glow of light.
From the far end of the street behind them a faint gong sounded and with an exclamation of annoyance the watchman hurried off to open the gate on the park side for the entrance of a motor car. He had scarcely passed beyond earshot when the inspector whispered to McCarty:
“What’s the idea, Mac? Did you hear what the watchman said? ‘B. P.’ didn’t belong here, in spite of the tag on the key-ring.”
“No more he did, sir,” McCarty agreed, but there was no disappointment in his tone. “I just want a word with the one that opens the door.”
There was no sound of footsteps from within but as McCarty finished speaking the door opened. Silhouetted against the soft light was the figure of a man, before whom, for the moment, even McCarty’s ready tongue was silenced. Dennis choked. They were confronted by a man who, though taller than the average of his race, was unmistakably Mongolian and clad in the flowing robes of his native land. He bowed slightly but in a dignified fashion, and then, as the visitors still remained silent, he asked:
“What is it you desire, please?”
His voice was high and singsong but it bore no trace of an accent.
