Thad grinned at him. 'You're not a fan of the late George Stark, I take it.'
'Frankly, no. But I have a deputy, Norris Ridgewick, who is. He had to explain to me what all
the hoop-de-doo was about.'
'Well, Stark messed with some of the conventions of the mystery story. Never anything so Agatha Christie as the scenario I just suggested, but that doesn't mean I can't think that way if I put my mind to it. Come on, Sheriff - had the thought crossed your mind, or not? If not, I really do owe my wife an apology.'
Alan was silent for a moment, smiling a little and clearly thinking a lot. At last he said, 'Maybe I was thinking along those lines. Not seriously, and not just that way, but you don't have to.apologize to your good lady. Since this morning I've found myself willing to consider even the most outrageous possibilities.'
'Given the situation.'
'Given the situation, yes.'
Smiting himself, Thad said: 'I was born in Bergenfield, New Jersey, Sheriff. There's no need to take my word when you can check the records for any twin brothers I may have, you know, forgotten.'
Alan shook his head and drank some more of his beer. 'It was a wild idea, and I feel a little like a horse's ass, but that's not completely new. I've felt that way since this morning, when you sprang that party on us. We ran down the names, by the way. They check out.'
'Of course they do,' Liz said with a touch of asperity.
'And since you don't have a twin brother anyway, it pretty well closes the subject.'
'Suppose for a second,' Thad said, 'just for the sake of argument, that it did happen the way I suggested. It would make a hell of a yarn . . . up to a point.'
'What point is that?' Alan asked.
'The fingerprints. Why would I go to all the trouble of setting up an alibi here with a fellow who looked just like me . . . then bugger it all by leaving fingerprints at the scenes of the murders?'
Liz said, 'I bet you really will check the birth records, won't you, Sheriff'
Alan said stolidly: 'The basis of police procedure is beat it until it's dead. But I already know what I'll find if I do.' He hesitated, then added, 'It wasn't just the party. You came across as a man who was speaking the truth, Mr Beaumont. I've had some experience telling the difference. So far as I've been able to tell in my time as a police officer, there are very few good liars in the world. They may show up from time to time in those mystery novels you were talking about, but in real life they're pretty rare.'
'So why the fingerprints at all?' Thad asked. 'That's what interests me. Is it just an amateur with my prints you're looking for? I doubt it. Has it crossed your mind that the very quality of the prints is suspect? You spoke of gray areas. I know a little bit about prints as a result of the research I did for the Stark novels, but I'm really quite lazy when it comes to that end of the job - it's so much easier just to sit there in front of the typewriter and make up lies. But don't there have to be a certain number of points of comparison before fingerprints can even be entered into evidence?'
'In Maine it's six,' Alan said. 'Six perfect compares have to be present for a fingerprint to be admitted as evidence.'
'And isn't it true that in most cases fingerprints are only half-prints, or quarter-prints, or just smudgy blurs with a few loops and whorls in them?'
'Yeah. In real life, criminals hardly ever go to WI on the basis of fingerprint evidence.'
'Yet here you have one on the rear-view mirror which you described as being as good as any print rolled in a police station, and another all but molded in a wad of gum. Somehow that's the one that really gets me. It's as if the fingerprints were put there for you to find.'
'It's crossed our minds.' In fact, it had done a good deal more. It was one of the most aggravating aspects of the case. The Clawson murder looked like a classic gangland hit on a blabbermouth: tongue cut out, penis in the victim's mouth, lots of blood, lots of pain, yet no one in the building had heard a goddamn thing. But if it had been a professional job, how come Beaumont's prints were all over the place? Could anything which looked so much like a frame not be a frame? Not unless someone had come up with a brand-new gimmick. In the meantime, the old maxim still held good with Alan Pangborn: if it walks like a duck, quacks like a duck, and swims like a duck, it's probably a duck..'Can fingerprints be planted?' Thad asked.
'Do you read minds as well as write books, Mr Beaumont?'
'Read minds, write books, but honey, I don't do windows.'
