I thought: "Psi-man, you are trapped!"
He thought: "I've killed before, Schnell. Why shouldn't I profess helplessness and innocence, and accuse you and the whole Police Department of the stupid and wanton death of my beloved daughter?"
"Because you've erred, Psi-man Wood."
"Ah, now I have proof! You're a Psi-man, too!"
"Who—me?" I thought without a visible change in my expression for Florence Wood to see. "You're the one who erred, Wood. You neglected the rules."
"Bah—the law! Stupid law—"
"Not so stupid, Wood. The law is really very sensible. It's strong, Wood, and it fosters the strength that comes of following it. So you see, Psi-man Wood, by never, never making any overt use of my talent, by never admitting that I know more than any clever man can see and deduce from what he knows—it has now become quite obvious to Chief Weston that if any such shenanigans as extra-sensory manipulation of this bank-vault door take place—you're the only one suspected of parapsychic power!"
And then the time-lock setting dials clicked around, their tiny noise muted by the glass door. They came around until they pointed to the present time. Then came the louder manipulation of outside dial lock, the heavy click of massive tumblers, and then the solid turning sound of wheel and mighty lever. The vault door swung open.
