The fourth witness waited near the study's far window, and Briar recognized Elsie immediately despite her elaborate costume, a sharp, expensive gown that suited her performance's evident hostility.
ELS: If you're here to ask whether I wanted Aldric Fenmore dead, the answer is obviously yes, though wanting and doing remain, I'd point out, two entirely separate matters.
ROS: That's remarkably direct.
ELS: I see no reason for subtlety. Everyone at that dinner knew about our rivalry. He undercut my prices for three straight seasons, deliberately, purely to drive me from the eastern trade routes. I've made no secret of my feelings toward the man, living or otherwise.
BRR: Where were you when he died?
ELS: In the dining hall, with the other guests, in full view of at least three people who could confirm as much, which I imagine makes me considerably less interesting as a suspect than you'd hoped.
She said it with a small, satisfied smile, the particular pleasure of someone playing morally sharp-edged but ultimately eliminable, and Briar, noting the specific alibi's apparent solidity, felt something in the puzzle's shape shifting toward a smaller, more manageable set of possibilities. They moved to the final witness.
Instructor Julian waited in a small side chamber dressed as the household physician, and Briar noted immediately the particular clinical precision he brought to the role, considerably more detailed and technically accurate than any of the previous witnesses' performances had managed.
JUL: I examined him myself, shortly after he was discovered. Heart failure, most likely. He'd suffered from a weak heart for years, a condition I'd been treating him for privately.
ROS: What time would you estimate death occurred?
JUL: Based on the body's condition when I examined it, I'd place it within the hour before he was discovered. Perhaps slightly before the other guests retired for the evening.
He delivered the assessment with total, professional confidence, the particular authoritative certainty of someone whose expertise the investigators had little immediate cause to question, and Briar, listening, found himself, for a long moment, entirely prepared to accept the physician's testimony at face value. Rosalind, beside him, had gone very still.
ROS: The wine glass.
She said it quietly, almost to herself, and crossed back toward the study's center where the overturned glass still sat, its dark stain spread across the rug beneath it, and Briar, following her, watched her crouch beside it with sudden, focused attention.
ROS: What kind of stain does this look like to you?
Briar examined it properly for the first time, really examined it, and felt something click into place with the particular satisfying certainty of a puzzle's final piece finding its correct position.
BRR: It's spread too widely for a quick spill. Look at the edges, they're gradual, not sharp. This wasn't knocked over suddenly. It leaked out slowly, over time, after he was already down.
ROS: Which means-
BRR: Which means whatever was in that glass took time to work. A slow-acting poison, not something that would kill within minutes.
They looked at each other, the same realization arriving in both of them at nearly the identical moment, and Briar felt the particular electric urgency of a solution finally, properly assembling itself.
BRR: The physician said death occurred within the hour before discovery. But if the poison was slow-acting, and the glass leaked out gradually rather than spilling all at once-
ROS: Then death occurred considerably earlier than he claimed.
BRR: Which he would know. As the physician. He'd know exactly how long that particular poison took to work, because-
He turned back toward the small side chamber, the whole shape of the mystery finally, completely visible.
BRR: Because he's the one who administered it.
He said it aloud, clearly, loud enough to carry, and the proctor, who had been observing from the room's edge, stepped forward with a small, satisfied nod.
PROC: Colton, Briar. You've named your culprit. State your full reasoning.
Briar gathered himself, the pieces settling into their final, complete shape.
BRR: Instructor Julian, playing the physician, poisoned Aldric Fenmore. The wine glass shows evidence of slow leakage rather than a sudden spill, indicating the poison took considerable time to fully work. But the physician's own testimony placed death within the hour before discovery, a timeline that doesn't match the physical evidence at all. He would have known the poison's actual working time, being the one with medical expertise and, we can reasonably infer, access to the poison itself. The false timeline was meant to obscure his own involvement, likely providing himself a false alibi for whenever the actual poisoning occurred.
The proctor consulted a small card.
PROC: And motive?
Briar considered this, working back through everything they'd gathered.
BRR: The business partner. Cornelius, Finn's character. He mentioned financial records he shouldn't have mentioned, twice, suggesting embezzlement he was desperate to hide. I'd guess the physician was paid to eliminate Fenmore before the embezzlement was discovered, making it look like natural causes given his known heart condition. A convenient cover, if you already knew the man's medical history intimately.
The proctor's expression shifted into open, approving satisfaction.
PROC: Correct. Full marks, Colton, Briar. Congratulations.
The staged room, for one suspended moment, held its collective silence, and then Instructor Julian, breaking character entirely, offered a small, genuinely impressed nod from the side chamber.
JUL: Well reasoned. Most competitors miss the leakage pattern entirely.
Rosalind, beside Briar, let out a breath that carried real, ungrudging admiration rather than any disappointment.
ROS: That was excellent deduction.
BRR: You spotted the wine glass first.
ROS: You made the connection to the timeline faster than I did. Credit where it's due.
She extended a hand, and Briar, shaking it, found the whole competitive tension of the past hour resolving into something considerably warmer, the particular mutual respect of two people who had genuinely enjoyed matching wits against each other, regardless of the final outcome.
ROS: Corin didn't exaggerate about your group, you know. He said you were all considerably more interesting than most people he'd met. I begin to see what he meant.
BRR: High praise, from him.
ROS: The highest, actually, though he'd never admit as much directly.
They left the staged study together, the whole elaborate scenario already being reset for the next pair of competitors, and Briar, stepping back out into the cold festival morning, found the whole disorienting, competitive final week finally, properly worth it, the particular satisfaction of a puzzle solved and a rivalry conducted with genuine mutual respect rather than any real bitterness settling comfortably into him. Somewhere behind him, he could hear Finn already loudly, enthusiastically recounting his own performance to anyone who'd listen, apparently having decided that his role as an unconvincing suspect had been, in his own estimation, a triumphant piece of theater regardless of how thoroughly it had actually implicated him. Briar, listening, found himself laughing properly for the first time all morning.
