"Careful. Even subvocalized conversation is distracting." The mechanism concealed within his body was silent for an instant and then continued: "His blood pressure is rising, breathing is faster. At a time like this, he may be ready to verbalize why he wants to murder you. This is critical."

"That's no lie," agreed Cassal bitterly. The lighter was in his hand. He clutched it grimly. It was difficult not to look back. The darkness assumed an even more sinister quality.

"Quiet," said Dimanche. "He's verbalizing about you."

"He's decided I'm a nice fellow after all. He's going to stop and ask me for a light."

"I don't think so," answered Dimanche. "He's whispering: 'Poor devil. I hate to do it. But it's really his life or mine'."

"He's more right than he knows. Why all this violence, though? Isn't there any clue?"

"None at all," admitted Dimanche. "He's very close. You'd better turn around."


Cassal turned, pressed the stud on the lighter. It should have made him feel more secure, but it didn't. He could see very little.

A dim shadow rushed at him. He jumped away from the water side of the alley, barely in time. He could feel the rush of air as the assailant shot by.
