They found him like this, just two days ago. Nobody's seriously tried to diagnose him yet, let alone treat him; all the other crises got in the way. But he's not much trouble, the nurses say, he just can't take care of himself. What they mean is, he can't feed himself and he wears a diaper. He ignored their little hint that he could help them with either of those jobs; there are some things a man just shouldn't do for another man. But he's not mad that they suggested it. Hell, they're even tireder than he is. They're taking good care of Radley, overall. Doing the best you could expect.
There was talk of bringing in experts from out of state, psychologists, neurologists, whatever, to figure out what happened. Pembrooke can't help with any of that; he's not a doctor, he's a cop. And that might turn out to matter, because he doesn't think Radley had a stroke, or a nervous collapse -- at the age of thirty-four! Get serious. This isn't something that happened to Radley, it's something someone did to him. It's just intuition, for now, but it fits. Way too much weird shit's been going on around Raymond recently. The Merrill boy vanished, and suddenly turned up again, rescued by an "angel". This weird, much-too-powerful storm. Radley's collapse. And Lane himself, and all the indescribably weird shit they found in his basement. It isn't that a bunch of weird things happened at the same time just by chance; that's not how the world works. They're all connected, even if Pembrooke can't see how or why yet, and that means each of them is a lead on all the others.
He started with Lane's papers. That's the other reason he keeps visiting the hospital: they have their own generator, and they leave the lights on at night. It's better for reading than a flashlight, and his wife's not around to bitch about it. Not a lot of Lane's stuff was in English, but there's some. Pembrooke took a few things home with him, Sunday morning, which you're not really supposed to do on an active crime scene, but Lane's basement is such a mess that he doubts anyone will notice. He skipped the books; they all have titles like "Notes on the Correspondence of Aleph and the Crown", or "The Qabalistic Tarot: a Textbook of Mystical Philosophy", which sounded too damned obscure to be useful. He's not trying to teach himself enough of...whatever this is...to fix Radley himself. He's trying to figure out where Lane went, or who he was talking to. Someone he could stick in Raymond's one and only jail cell, and sweat a little until they cough up some explanations. No progress yet.
They need to find Lane; they put out a BOLO Sunday morning, but of course the storm jammed that up. If Lane got out ahead of it he could be on Mars by now, but maybe the staties will come up with a lead. He should probably at least skim those stupid books, in case there's a section on practical hypnosis or something. And he needs to go upstairs talk to the Merrill kids, no matter how much that whole story pisses him off. If there's an angel running around saving people, how come she isn't here, in this room, huh? Yeah. He needs to get to the bottom of what happened there, find that so-called angel and make her explain what she knows.
It's harder detective work than Raymond usually offers. Frankly, Raymond doesn't usually offer mysteries of any kind, just the usual small-town tide of drunk teens and domestic disturbances. A few CPS cases, here and there. Difficult in its own way, but nothing you'd have to think hard about, which is usually something Pembrooke likes about the job.
