he was in the washroom, much as he would have welcomed an excuse for conversation. He dawdled his way through the door into the corridor, not liking the thought of inflicting his presence upon Beryl and Parrish. That meant he would have to walk back as far as the spare conference room to find a phone. "Of course, there's the lab," he muttered. That was only a few steps away, and he could hardly do much damage between the door and the phone. Reaching the end of the corridor once more, he decided to make one last try at Lydman's door. Again, there was no reply to his knock, so he turned away to the laboratory door and entered. He was faced by a vista of tables, workbenches with power tools, and diverse assemblies of testing apparatus, most of the latter dusty and presenting the appearance of gold-bergs knocked together for temporary use and then shoved aside until someone might need a part from one of them. By far the greater space, however, was occupied by shelves and crates and stacks of small cartons or loosely wrapped packages in which various gadgets seemed to be stored after plans of them had been transmitted to the field. Half a dozen large files for drawings and blueprints reached nearly to the ceiling. Racks of instruments in relatively recent use or consideration stood here and there among the tables and workbenches. To Westervelt's right, near the far wall behind which lay the communications room, he caught sight of a prowling figure. He recognized Lydman's broad shoulders and hesitated. The ex-spacer had paused to examine a gadget lying on one of the tables. From Westervelt's position, it appeared to be a wristwatch or something similar. Lydman picked it up and turned toward a part of the wall where a thick steel plate had been fastened to an insulated partition of brick. He raised the "watch" to eye level, as if aiming. A thin pencil of white flame leaped from the instrument to spatter sparks against the already scarred and stained steel. Sucked up by the air-conditioning, the small puff of smoke disappeared so quickly that Westervelt realized that the scorched odor was entirely in his imagination. Lydman replaced the instrument casually before strolling over to another table. He inspected an open pack of cigarettes with a grim smile, but let them lie there in plain sight. Westervelt reminded himself never to grub one of those, just on general principles.
