“Beastly night!” Verbeck confided to himself, and put his head beneath the covers.
He slept—and suddenly he awakened. A moment before he had been in the midst of a pleasant dream; now every sense was alert, and his right hand, creeping softly under the cover, reached the side of the bed and grasped an automatic pistol that hung in a rack there.
From the adjoining room—his library—there came no flash of an electric torch, no footfall, no sound foreign to the apartment, nothing to indicate the presence of an intruder. Yet Verbeck sensed that an intruder was there.
He slipped quietly from the bed, shivering a bit because of the cold wind, put his feet into slippers, and drew on a dressing gown over his pajamas. Then, his pistol held ready for use in case of emergency, he started across the bedroom, taking short steps and walking on his toes.
A reflection entered the room from the arc light on the nearest street corner. This uncertain light was shut off for an instant, and Verbeck whirled quickly, silently, to find another man slipping up beside him. It was Muggs—a little, wiry man of uncertain age, who had been in Verbeck’s employ for several years, valet at times, comrade in arms at times, willing adventurer always. Muggs bent forward until his lips were close to Verbeck’s ear.
“I heard it, too, boss,” he said. “Somebody in the library!”
Verbeck nodded; they crept nearer the door. Inch by inch, Verbeck pulled aside one of the curtains, until they could peer into the other room. A gleam from the corner arc light penetrated the library, too. It revealed the interior of the room in a sort of semi-gloom, causing elusive shadows that flitted here and there in such fashion that they scarcely could be distinguished from substance. Also, it revealed an open window near the fire escape—and it showed the form of a man standing before Verbeck’s antique desk in a corner.
Muggs bent beneath his master’s arm to see better. He felt Verbeck grip his shoulder, and looked up to find him indicating the open window. Like a shadow, Muggs, who also held a weapon in his hand, slipped through the curtains, crept along the wall, and advanced toward that window to cut off the intruder’s retreat.
