The all-night poker game at Harry Brambaugh's was, of course, the basis of it. But he'd worked things out so that game would alibi him for all night no matter what happened. Someone in the game might or might not buy the diamond ring to let him play. And if someone did buy it, he might still go broke within the first hour, and that would be no good at all. His alibi had to be for all night, clear up to dawn.

He'd told the psycho, in effect, that an attack on Ruth would be safe any time after midnight; he couldn't possibly pinpoint it by suggesting a specific time or even a deadline. And for all Ray knew the guy might as easily make his call at two or three in the morning as at half past twelve. Besides, even if he had any way of timing it, he didn't dare get home too soon after the psycho had left. The minute he got home and found Ruth dead he'd have to call the police—and if she were freshly dead they'd still suspect him of having killed her and having done it in such a way as to throw suspicion on the psycho. He didn't dare find her until she'd been dead at least a couple of hours, and with him having a solid alibi for the time at which she'd died.

To be safe he didn't dare get home before five in the morning and six would be better.

So, since the psycho had left, he'd been planning carefully; he was going to have an all-night alibi from Harry and whoever else was in the game, whether or not he could sell the ring and whether or not he went broke quickly if he did sell it. All it took was the right build-up.

Harry had a downtown apartment, only a block and a half from here. Five minutes walk and if he left at five of twelve he could establish the time of his arrival by saying "Cold on the stroke of midnight," when he walked into the room. That wouldn't sound suspicious or as though he was trying to establish an alibi because it was a phrase he often used anyway. So did some of the other boys. It was a quotation from a poem or something, and it was a cliché that fitted in any time the question of time came up at or within a minute of midnight.

Second step: The minute he got in he'd tell Harry he felt lousy, had an upset stomach and a headache. He'd say it would probably wear off, but did Harry have a Bromo-Seltzer or an Alka-Seltzer around, and maybe a couple of aspirin tablets too. And Harry would have; Harry had a bad stomach and headaches himself and was always well stocked with patent medicines; Harry would give him something and he'd take it. Point made.

Then, at the poker table but before sitting down, he'd explain apologetically that he was short on cash but had a hell of a bargain in a diamond ring, if anyone might be interested in buying it, and he'd pass it around. He'd try to get a hundred, but settle for fifty if someone wanted it but quibbled about price. Either someone would buy it or no one would buy it.

If no one bought, well, he'd laid his groundwork, by convincing Harry he was sick. He'd say he didn't feel up to going home right away, and would Harry mind if he lay down on the sofa a while first. Harry had a comfortable sofa right in the living room, the room in which they played cards. Lying there he'd be in sight of everyone in the game. And Harry was a nice guy; he certainly wouldn't mind. That sofa had been used before for similar purposes; once in a while someone got tired in the middle of a game and wanted to rest a while and then get back in.

So he'd pretend to go to sleep on the sofa—or really go to sleep if he could. And stay there till the game broke up, which was never before five o'clock.

Same deal with a minor variation if he sold the ring but lost the money too soon. His upset stomach and headache would have come back by then; he'd take more Alka-Seltzer and aspirin and then lie down a while to give them a chance to work.
