"They're doing the same thing on Tom's back, right here," I told Joe. "Only you can't grow fingerprints by carniculture, the way you can human tissue for grafting. They had to have palm and finger surfaces from a pair of real human hands. A pauper, dying in a free-treatment ward, her body shoved into a mass-energy converter." Then I thought of something else. "That showoff trick of his, crushing out cigarettes in his palm," I said. Bish nodded commendingly. "Exactly. He'd have about as much sensation in his palms as I'd have wearing thick leather gloves. I'd noticed that. "Well, six months going, and a couple of months waiting on reports from other planets, and six months coming, and so on, it wasn't until the _Peenemünde_ got in from Terra, the last time, that I got final confirmation. Dr. Watson, you'll recall." "Who, you perceived, had been in Afghanistan," I mentioned, trying to salvage something. Showing off. The one I was trying to impress was Walt Boyd. "You caught that? Careless of me," Bish chided himself. "What he gave me was a report that they had finally located a man who had been a staff surgeon at this hospital on Baldur at the time. He's now doing a stretch for another piece of malpractice he was unlucky enough to get caught at later. We will not admit making deals with any criminals, in jail or out, but he is willing to testify, and is on his way to Terra now. He can identify pictures of Anton Gerrit as those of the man he operated on fourteen years ago, and his testimony and Ernestine Coyón's fingerprints will identify Ravick as that man. With all the Colonial Constabulary and Army Intelligence people got on Gerrit on Loki, simple identification will be enough. Gerrit was proven guilty long ago, and it won't be any trouble, now, to prove that Ravick is Gerrit." "Why didn't you arrest him as soon as you got the word from your friend from Afghanistan?" I wanted to know. "Good question; I've been asking myself that," Bish said, a trifle wryly. "If I had, the _Javelin_ wouldn't have been bombed, that wax wouldn't have been burned, and Tom Kivelson wouldn't have been injured. What I did was send my friend, who is a Colonial Constabulary detective, to Gimli, the next planet out. There's a Navy base there, and always at least a couple of destroyers available. He's coming back with one of them to pick Gerrit up and take him to Terra. They ought to be in in about two hundred and fifty hours. I thought it would be safer all around to let Gerrit run loose till then. There's no place he could go. "What I didn't realize, at the time, was what a human H-bomb this man Murell would turn into. Then everything blew up at once. Finally, I was left with the choice of helping Gerrit escape from Hunters' Hall or having him lynched before I could arrest him." He turned to Kivelson. "In the light of what you knew, I don't blame you for calling me a dirty traitor." "But how did I know..." Kivelson began.
