"Then it's still there," he said slowly. "Judge Reed ordered the room sealed up until after the trial. And then there's the closet.... Were you wearing gloves that afternoon, Miss North?"

She said, "No. You're thinking of fingerprints?"

"If you're telling the truth," he said, "there's almost certain to be some of your prints on the inside of that closet door--maybe even on that length of metal, if we can find it."

She said almost carelessly: "That's all you'd need to clear Paul Cordell, isn't it?"

"It would certainly help." He swung around in the chair, scooped up the telephone and gave a series of rapid-fire orders, then dropped the instrument on its cradle and turned back to where she sat watching him curiously.

He said, "A few things I still don't get. Like this business of your standing two feet off the floor in a ball of blue light. And the flashes of light just before Cordell heard his wife and Gilmore fall to the floor. Even the s.n.a.t.c.hes of conversation he caught while still in the hall. He couldn't have dreamed all that stuff up--at least not without _some_ basis."

She had opened her bag and taken out a cigarette. Kirk ignited one of his kitchen matches and she bent her head for a light. He could see the flawless curve of one cheek and the smooth cap of blonde hair, and he resisted the urge to pa.s.s a hand lightly across both. Something was stirring inside the Lieutenant--something that had long been absent.

And, he reflected wryly, all because of a girl who had just finished confessing to two particularly unpleasant murders.

Naia North raised her head and their eyes met--met and held. Her lips parted slightly as she caught the unmistakable message in those gray-blue depths....

The moment pa.s.sed, the spell was broken and she leaned back in the chair and laughed a little shakily. "I read about those statements of his in the papers, Lieutenant. I think perhaps I can at least partially explain them. As I remember it, there were several Bunsen burners lighted on the laboratory bench near that window. They give off a blue flame, you know, and I must have been standing near them when Paul Cordell came charging in. In his confused frame of mind, he may have pictured me as being in a ball of flame."

"Sounds possible," the man admitted, frowning. "What about those flashes of light?"

"You've got me there. Unless they were reflections of sunlight through the window--from the windshield of a pa.s.sing car, perhaps."

"And the things he heard you and Gilmore saying?"

She shook her head regretfully.

"There I'm simply in the dark, I don't see how he could have twisted what little we said into the utterly fantastic nonsense he claims to have heard."

Kirk rubbed a hand slowly along the side of his neck, still frowning.

"He _could_ have confused that length of metal in your hand as a gun....

Well--" his shoulders lifted in the ghost of a shrug--"it all seems to add up. Except one thing: Cordell had been tried and convicted, leaving you in the clear. Why come down here voluntarily and stick your lovely head in a noose?"

The girl smiled faintly. "'Lovely head', Lieutenant?"

Kirk flushed to the eyebrows. "That slipped out.... Why the confession?"

She said soberly: "I was so sure they'd let him off. When you _know_ someone's innocent you can't realize that others won't know it too, I suppose. But when I learned he'd been found guilty and actually condemned to die ... well, I know it sounds n.o.ble and all that but I couldn't let him go to his death for something I'd done. Surely such a thing has happened before in your experience, Lieutenant."

He watched as she drew smoke from the cigarette deeply into her lungs and let it flow out in twin streamers from her nostrils. Only rich men, he thought, could afford a woman like this, and somehow it made him resentful. What right did she have to walk in here and flaunt a body like that in his face? She went with mink stoles and cabin cruisers and c.o.c.ktails at the Sherry-Netherland, and her shoe bill would exceed his yearly salary. She would be competent and more than a little cynical and not too concerned with morals or the lack of them. That kind of woman could kill--and would kill, on the spur of the moment and if the provocation was strong enough.

"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?"

Kirk smiled crookedly. "You're forgetting this case _was_ solved--over a month ago. You any idea what it can mean to a politician to have to admit publicly that he's made a mistake? Especially a mistake that's going to get all the publicity this one's bound to? 'District attorney railroads innocent man!' 'Tragic miscarriage of justice averted only by chance!' Stuffy editorials in the opposition press about incompetence in high offices and how the voters must keep out anybody who goes around executing the innocent and helpless. Looks like Arthur Kahler Troy is going to be a mighty unpopular man around these parts--and election less than five months away!"

He glanced up at the office clock. It was nearly nine o'clock in the evening, and both of them were showing signs of wear. Kirk left his chair and went over to the water cooler, drank two cupfuls and brought one back to the girl. She thanked him with a wan smile and gulped down the contents.

He took the empty paper container and crumpled it slowly. "Might as well get hold of him," he muttered. "It's going to be mighty d.a.m.ned rough, sister. You sure you want to go through with it?"

She lifted an eyebrow at him. "That's a peculiar question for a homicide officer to ask, isn't it?"

"I suppose so." His eyes shifted to the phone on his desk, stayed there for a long moment. Then he shrugged hugely and picked up the receiver....

It was well after two in the morning before Martin Kirk reached his apartment. He showered and got into a fresh pair of pajamas and went into the small, spa.r.s.ely furnished living room. He moved slowly and with no spring in his step, and the set of his features was harsh and strained in the soft light from the floor lamp.

Troy had been even more difficult than he'd feared. What had begun as plain irritability at being disturbed, had pa.s.sed by successive stages to amused disbelief, open anger and finally reluctant conviction that Paul Cordell was innocent of the crimes for which he had been sentenced to die.

A male stenographer from his staff was called in and Naia North dictated a complete statement which she signed. Troy questioned her for nearly two hours, getting in every possible angle of her private life as well as minute details of her actions on the day of the murders. Kirk had not been present during that part of the night, but he figured it wouldn't be much different from what he'd heard many times before.

He mixed himself a drink, and was surprised to discover that his hands were shaking noticeably. Well, why not? A day like the one he'd just been through would put the shakes in Grant's Tomb. Even as he made the excuse, he knew it wasn't the real reason. There had been cases that had kept him on his feet for as much as forty-eight hours--cases where men had pointed guns at him and pulled the triggers--and the shakes never came.

No, it was the girl. Naia North. Naia--a strange name. But no stranger than the girl herself. Now how about that? Why should he think her strange? Because she'd taken a life or two? h.e.l.l, lots of people did that and no one called them strange. Criminal or unmoral or greedy or angry, yes. But not strange. She looked like other women--only a lot better. She dressed like them, walked like them, talked like them. So why strange?

Because she _was_ strange. Nothing you could put your finger on made her that way, but that's the way she was.

He threw his cigar savagely into the fireplace. He went over and made another drink and poured it down fast and another one after it, right on its heels. Then he went to bed. Tomorrow--today, rather--was a work day and work days were tough days and he needed his rest.

He didn't get much of it, though. The phone woke him a few minutes after seven o'clock. It was Arthur Kahler Troy at the other end and the D. A.

was too angry to be coherent.

It seemed Naia North had disappeared from her locked cell during the night.
