“Now, if an angel can kill, it is obvious that Snookums would not dare attack an angel, especially if he had been ordered to do so by a human.”
“Just a minute, Commander,” said Dr. Fitzhugh, corrugating his face in a frown. “That doesn’t hold. Even if an angel could blast him, Snookums would attack if ordered to do so. The Second Law of obedience supersedes the Third Law of self-preservation.”
“You’re forgetting one thing, Doctor. An angel of God would know who had ordered the attack. It would be the human who ordered the attack, not Snookums, who would be struck by Heavenly Justice. And the First Law supersedes the Second.”
Fitzhugh nodded. “You’re right, of course.”
“Very well, then,” Mike continued, “since the killer could not get Snookums to do me in, he had to find another tool. He picked Lieutenant Mellon.
“He figured that Mellon was in love with Leda Crannon. Maybe he was; I don’t know. He figured that Mellon, knowing that I was showing Miss Crannon attention, would, under the influence of the lysurgic acid derivative, try to kill me. He may even have suggested it to Mellon after Mellon had taken a dose of the drugged wine.
“But that plan backfired, too. Mellon didn’t have that kind of mind. He knew my attentions and my intentions were honorable, if you’ll pardon the old-fashioned language. On the other hand, he knew that von Liegnitz had a reputation for being—shall we say—a ladies’ man. What happened after that followed naturally.”
Mike watched everyone at the table. No one moved.
“So the killer, realizing that he had failed twice, decided to do the job himself. First, he went into the low-power room and slugged the man on duty. He intended to kill him, but he didn’t hit hard enough. When that man wakes up, he’ll be able to testify against the killer.
“Then the killer ordered Snookums to tear out the switches. He had made sure that Snookums would be waiting outside. Before he called Snookums in, of course, he had to put the duty man in a tool closet, so that the robot wouldn’t see him. He told Snookums to wait five minutes and then smash the switches and head back to his cubicle.
