'Yeah, that's a possibility. Although if this guy also looks like your husband, Mrs Beaumont - '
'Liz.'
'Okay, Liz. If he looks like your husband, he'd look like Thad Beaumont with blonde hair, wouldn't he?'
Liz looked fixedly at Thad for a moment and then began to giggle.
'What's so funny?' Thad asked.
'I'm trying to imagine you blonde,' she said, still giggling. 'I think you'd look like a very depraved David Bowie.'
'Is that funny?' Thad asked Alan. 'I don't think that's funny.'.'Well . . .' Alan said, smiling.
'Never mind. The guy could have been wearing sunglasses and deelie-boppers as well as a blonde wig, for all we know.'
'Not if the killer was the same guy Mrs Arsenault saw getting into Homer's truck at quarter of one in the morning of June first,' Alan said.
Thad leaned forward. 'Did he look like me?' he asked.
'She couldn't tell much except that he was wearing a suit. For what it's worth, I had one of my men, Norris Ridgewick, show her your picture today. She said she didn't think it was you, although she couldn't say for sure. She said she thought the man who got into Homer's truck was bigger.' He added dryly: 'That's one lady who believes in erring on the side of caution.'
'She could tell a size difference from a picture?' Liz asked doubtfully.
'She's seen Thad around town, summers,' Alan said. 'And she did say she couldn't be sure.'
Liz nodded. 'Of course she knows him. Both of us, for that matter. We buy fresh stuff at their vegetable stand all the time. Dumb. Sorry.'
'Nothing to apologize for,' Alan said. He finished his beer and checked his crotch. Dry. Good. There was a light stain there, probably not anything anyone but his wife would notice. 'Anyhow, that brings me to the last point . . . or aspect . . . or whatever the hell you want to call it. I doubt if it's even a part of this, but it never hurts to check. What's your shoe-size, Mr Beaumont?'
Thad glanced at Liz, who shrugged. 'I've got pretty small paws for a guy who goes six-one, I guess. I take a size ten, although half a size either way is - '
'The prints reported to us were probably bigger than that,' Alan said. 'I don't think the prints are a part of it, anyway, and even if they are, footprints can be faked. Stick some newspaper in the toes of shoes two or even three sizes too big for you and you're set.'
'What footprints are these?' Thad asked.
'Doesn't matter,' Alan said, shaking his head. 'We don't even have photos. I think we've got almost everything on the table that belongs there, Thad. Your fingerprints, your blood-type, your brand of cigarettes - '
'He doesn't - ' Liz began.
Alan held up a placatory hand. 'Old brand of cigarettes. I suppose I could be crazy for letting you in on all this - there's a part of me that says I am, anyway - but as long as we've gone this far, there's no sense ignoring the forest while we look at a few trees. You're tied in other ways, as well. Castle Rock is your legal residence as well as Ludlow, being as how you pay taxes in both places. Homer Gamache was more than just an acquaintance; he did . . . would odd jobs be correct?'
'Yes,' Liz said. 'He retired from full-time caretaking the year we bought the house - Dave Phillips and Charlie Fortin take turns doing that now - but he liked to keep his hand in.'
'If we assume that the hitchhiker Mrs Arsenault observed killed Homer - and that's the assumption we're going on - a question arises. Did the hitchhiker kill him because Homer was the first person to come along who was stupid enough - or drunk enough to pick him up, or did he kill him because he was Homer Gamache, acquaintance of Thad Beaumont?'
'How could he know Homer would come along?' Liz asked.
'Because it was Homer's bowling night, and Homer is - was - a creature of habit. He was like an old horse, Liz; he always went back to the barn by the same route.'
'Your first assumption, ' Thad said, 'was that Homer didn't stop because he was drunk but because he recognized the hitchhiker. A stranger who wanted to kill Homer wouldn't have tried the hitchhiking ploy at all. He would have figured it for a long shot, if not a totally lost cause.'.'Yes.'
'Thad,' Liz said in a voice which would not quite remain steady. 'The police thought he stopped because he saw it was Thad . . . didn't they?'
'Yes,' Thad said. He reached across and took her hand. 'They thought only someone like me - someone who knew him - would even try it that way. I suppose even the business suit fits in. What else does the well-dressed writer wear when he's planning on doing murder in the country at one o'clock in the morning? The good tweed, of course . . . the one with the brown suede patches on the elbows of the jacket. All the British mysteries insist it's absolutely de rigueur.'
He looked at Alan.
