ASK
Where were you between ten and eleven o’clock last night?
*sets down the coat tickets and folds her hands on the counter* Right here, as I said. The counter keeps you anchored — you can’t very well abandon it mid-evening with guests still inside. I had a few returns around quarter past ten, a gentleman collecting a grey overcoat, a lady who’d left her wrap. Nothing out of the ordinary. Is there a reason you’re asking about that window specifically?
cooperative
PRESS
The floor manager says the coat check was unmanned for nearly twenty minutes around half past ten. Where exactly were you?
*fingers tighten briefly on the edge of the counter* Twenty minutes. That’s — no, that’s not right. I may have stepped to the back for a moment, there’s a small storeroom just off the corridor where I keep the spare hangers and ticket rolls. A minute or two at most. Mr. Hendricks has a lot to watch on a busy night. I wouldn’t put too much weight on his sense of the clock when the floor is full. *pauses, smooths her apron again* If I was away from the counter it was for something entirely routine. That’s all.
defensive
CONFRONT
We found a hidden medicine bottle at the coat check counter. What was that doing there?
*goes very still* *hand moves instinctively toward the small photograph propped behind the counter, then stops* I — that’s — *exhales slowly, jaw tightening* I have trouble sleeping. Have done for months. Anyone who knows me could tell you that. The prescription was mine and I kept it close because I intended to take a measure on my break. There’s nothing sinister in a woman keeping her medicine near to hand. *eyes harden* I’d like to know who went through my things, Detective. That counter is my workspace. You’d do better asking questions about the people who had actual reason to want the victim dead rather than rifling through a coat girl’s belongings.
hostile
CONFRONT
We found a receipt in your handbag — you purchased an engraved item that doesn’t belong to you, three days before the murder. Explain that.
*stops mid-word* *her hand drops from the photograph and she sits down on the small stool behind the counter as though her legs simply — stopped* *for a long moment she doesn’t speak, just looks at the evidence in your hand with an expression that has gone somewhere very far away* *when she finally looks up, her eyes are bright and her voice comes out wrong, too quiet* Where did you — *stops again*

SOLVED: "The Whitby Silence"
This reveals the complete solution to The Whitby Silence —
a real player's theory card from a finished investigation.
SOLVED: "The Whitby Silence" My theory: Ronald's fingerprints on the bottle pointed at him first — but he had no reason to kill the star his entire production depended on. The recording log was the turn: Beatrice signed herself out for a 'reel check' during the exact window, and the promotion memo explained why. Cordelia had blocked her from the Assistant Producer chair after eighteen years. The discarded bottle hidden in the sound booth — the original, swapped out and wrapped in an oil rag — proved she had doctored Cordelia's voice preparation with camphor and put the clean bottle back in her own workspace. First suspected: Ronald Prosser Turning point: Round 3 (switched to Beatrice Hodge) Breaking clue: "A second Vandell's bottle, wrapped in an oil-stained rag beneath curling 78rpm sleeves in the sound-booth wastebasket. Camphor concentration ten times therapeutic. Beatrice's fingerprints on the neck." Score: 162 — Veritas veritascase.com
