Mason nodded absently, tossed his key to the desk, and strode across to the stairway which led to the garage, the skirts of his raincoat kicked about by the long strides of his legs. The clerk watched him curiously, the extent of his interest shown by the manner in which he weighed Mason’s key in his hand before placing it in the proper receptacle.

The lawyer acknowledged the greeting of the garage man, slid in behind the wheel of his big coupe, and sent it roaring up the spiral ramp of the garage. As he left the shelter of the garage, the wind swooped down upon him. Sheeted rain beat solidly on the body of the car, streamed down the windshield. Mason turned on the windshield wiper, shifted cautiously into second, and eased the wheels through the curb-high flood at the gutter.

The headlights reflected back from miniature geysers of water mushrooming up from the pavement ahead. Mason eased the car into high gear and settled down to the chore of driving through the rain-swept, all but deserted streets.

He noticed that there were no cars parked in the block in front of his office building. Over in the parking station, where Mason rented a regular stall, were two of the nondescript cars of the Drake Detective Agency, and no others. He parked and locked his automobile, and stepped out into the storm. Rain beat against his face, cascaded in rivulets from his raincoat, spattered against his ankles. Mason, who detested umbrellas, shoved his hands down deep into the pockets of his raincoat, lowered his head against the force of the storm, and sloshed through the puddles which had collected in the parking place, to push against the swinging door in the lighted lobby of his office building.

Streaks of moisture which seemed fresh indicated that others were there ahead of him. He paused at the elevator, rang the night bell which summoned the janitor, and waited for a full minute before the sleepy-eyed Swede, who had charge of the basement and night elevators, brought a cage up to the lobby floor.

“Some rain,” the janitor said, and yawned.

Mason crossed over to look at the register which persons entering the building at night must sign. “Anyone for me, Ole?” he asked.

“Not yet,” the janitor said. “Maybe she rain so much they don’t come on schedule.”

“Someone down from Drake’s office a few minutes ago?” Mason asked.

“Yah.”
