"Yes, sir," said Strong grimly. "So the man who did it thought he was doing a complete job."
"Right," said Walters. "Assuming that it was sabotage."
"Anyone you suspect?"
"Not a living soul," replied Walters. "Every man in that hangar has been carefully screened by our Security Section. Background, history, everything. No, I think it really was an accident."
"Yes, sir," replied Strong, but not with the conviction he would like to have felt.
Pat Troy had been Professor Hemmingwell's foreman for nearly two years. It was his job to read the complicated blueprints and keep the construction and installation work proceeding on schedule. Troy lacked a formal education, but nevertheless he could read and interpret the complicated plans which the professor and his assistants drew up, and transform their ideas into actual mechanical devices. Professor Hemmingwell considered himself fortunate to have a man of Troy's ability not only as a co-worker, but as a close friend.
But Dave Barret did not like Troy, and he made this dislike obvious by giving Troy as much work as possible, mainly tasks that were beneath his ability, claiming he only trusted the trained scientists. Barret put the professor in the position of having to defend one to the other. He needed both men, both being excellent in their respective fields, and found it more and more difficult to maintain any kind of peaceful relationship between them. Barret, as Hemmingwell's chief assistant and supervisor of the project, was naturally superior in rank to Troy, and made the most of it. A placid, easy-going man, Troy took Barret's gibes and caustic comments in silence, doing his work and getting it finished on time. But occasionally he had difficulty in controlling his resentment.
The day after the accident, or sabotage attempt on the firing unit, the hangar was quiet, most of the workers still being psychographed. Troy, one of the first to be graphed, had been detained by the technicians longer than usual, but was now back at his bench, working on the unit. This incident gave Barret the opportunity he was looking for, and as he and Professor Hemmingwell strode through the hangar, he commented casually, "I hate to say this, sir, but I don't like the way Troy has been acting lately."
