"Well, Lieutenant?" She said it lightly, almost with disinterest.
Then Kirk was all right again, and he was looking at a woman who had just confessed to murder.
"You heard the phone call I made a moment ago, Miss North. Two men from the Crime Lab are already on their way to the University. If they find your fingerprints inside that closet, if they can turn up anything to prove you've been in Gregory Gilmore's laboratory, then you and that evidence and your confession get turned over to the D. A. and Paul Cordell will be on his way to freedom."
"And if those men don't find anything?"
"Then," he told her rudely, "you're just another crackpot and I'm tossing you and your phony confession out of here."
They found the fingerprints: several perfect ones on the inner door of the laboratory coat closet. But even more conclusive was their discovery of a short length of polished metal pipe among the dismantled parts of a Clayton centrifuge. At one end of the pipe were the imprints of four fingertips—at the other a microscopic trace of human blood.
"We had no business missing it the first time, Lieutenant," the Crime Laboratory technician told Kirk ruefully. "I'd a sworn we pulled that place apart last month. But this time we got the murder weapon and we got the prints—and those prints match the ones we took off that blonde. Hey, how about that, Lieutenant? I thought this Cordell guy did that job?"
Slowly Kirk replaced the receiver and eyed Naia North across the desk from him. "Looks like you're elected," he said somberly. "I'm telling you straight: the D. A. isn't going to like this at all—not even any part of it."
Her brow wrinkled. "I'm afraid I don't understand. Doesn't he want murder cases solved?"
