The house just northeast of Forks proper is very big, quite abandoned, and really easy to just walk right in if you're of a mind to. There are signs that people have been camping in it while hiking, but currently it is unoccupied by visitors, squatters, or any animals larger than a squirrel. There's been a fair amount of furniture but fewer small possessions left behind: couch, piano, dining table, wardrobe, armchair, kingsized bed. It's in extremely variable states of repair.
Well, now she is bored.
Elizabeth inspects the place closely, looking in particular for anywhere it might have been convenient for somebody to hide a body. (That is the likeliest possible reason why no one ever found the kid, after all.)
That wardrobe, for example! It seems pretty deep, and it's shut pretty firmly. Once she gets the door open, she's careful to wedge it that way with a reasonably sturdy chair before climbing inside past a surprisingly well-preserved selection of fur coats - she'd pull them out first if she thought there was actually a dead teenager in there, but odds are high that in any setting outside of a mystery novel somebody else would have found him by now.
There is plenty of snow. It is cold. There is a lit lamp-post.
And stepping into the spill of light from the lamp-post is a man just a little bit taller than she is, who has fur on his hoofed legs and a tail looped over his elbow and parcels in his hand and an umbrella in his other hand and a scarf round his neck and little pokey horns being little and pokey amongst his hair.
He reacts with much less aplomb to his surprise at seeing Elizabeth than did the pine trees. Dropped are all his carried possessions and the tail too.
Presently there is food! And tea! It is tasty. Tumnus tells stories about dancing at midnight with nymphs, about going on hunts for the wish-granting white stag, about adventuring with dwarves in deep mines seeking treasure, about how there was summer once and beautiful holidays where the forest folk would be visited by this or that grand personage and the rivers ran purple with wine. The part about summer seems to make him sad. He then plays a little straw flute, to cheer himself.
"Oh, just look at me, would you think to look at me that I'm the sort of Faun who'd find a Daughter of Eve wandering the woods, a harmless child who'd never done me any ill, and pretend to be friendly and invite her to my cave meaning all the while to occupy her until she asked to sleep there for the night all for the sake of turning her in to the White Witch?"
"Oh, of course I've lost my nerve now, but if she finds out I found a human and then let it go, she's sure to have my tail cut off and my horns sawn off and she'll wave her wand over my hooves till they've turned into wretched horse hooves of all things, and if she is in a specially bad mood perhaps after all that I will be turned into a statue until the thrones at Cair Paravel are filled and who knows when that shall happen, or whether it ever shall at all?"
She turns around.
She reaches, standing outside the wardrobe, into the wardrobe... and touches wood at the back, behind the coats.
She stands, staring at it meditatively, for a few seconds. Then she steps away, because she'd better hurry home, it's been—
—not even long enough for the angle of the shadows under the window to change.
So either not long at all, or very long indeed.
Elizabeth goes home in a hurry. She checks the clock. She looks in on Chris in her office and gets an absent-minded 'hi', from which she deduces that she has in fact been gone for just about long enough to bike to the abandoned house and back, and not to have had tea with a Faun and listen to his stories for hours in between, nor the day or days on top of that it would have taken for the sun to be at the same angle coming as going.
It's all right there in her mind palace, every detail she could store away, a whole new room tucked behind a wardrobe with notes about Fauns and winter and Christmas and the White Witch and the thrones at Cair Paravel. She doesn't think it was a dream. She doesn't think she imagined it. But all the evidence outside her head points to her having walked into that wardrobe, taken a very short nap with very vivid dreams, and then walked out again not five minutes later.
The problem continues occupying her mind for quite a while.
"Elizabeeeeth?" she calls, knocking on the door.
"Well, nobody knows. If you want the whole story - kid's name was Delaney Hammond, had some unfortunate middle names I can't quite remember, he was a year behind me in school but may've been he was held back. Family moved in, he vanished, ugly rumors started flying around - parents took a while to report it, could've been because he was the sort you'd expect to wander off without permission. May have done, anyway, but he didn't come back. Family and their chauffeur were inconsistent about where he'd been the last time they saw him or whether he'd have gone anyplace in particular, mother seemed sort of relieved for some reason - but there was no physical evidence to speak of, case is long cold."
"I wouldn't guess one of the parents did it," she says thoughtfully. "Because that wouldn't explain why the mom was relieved, even if she really, really didn't like him or something, she would've had to have been worried they'd get caught unless it was the dad that did it and she didn't even know, but that seems unlikely. The ransom theory has the same problem, but less of it. Driven away by bad treatment explains why the mom was relieved, though, if she wasn't the one treating him badly but wasn't brave enough to do anything about it herself."
"Most of my books are at Renée's house, mostly because that's where I am birthdays and Christmas and that's when I get most of my books, but the ones that are here are the ones that I've read and liked enough that I want them handy when I'm here and there isn't a really good bookstore around."
