Corporate Office · 2026-07-15
Four keycards, one sealed floor — and the CFO dead at his desk hours before his audit reaches the board.
The Corner Office is an office murder mystery game set on a sealed executive floor. At 12:40 a.m., a security guard on his final round found Gregory Marsh face-down at his desk in the corner office of Verent Capital's thirty-fourth floor, struck once from behind with the crystal deal trophy from his own shelf. His screen was still unlocked, the internal audit file open at its final page.
The floor seals itself to keycards after ten. Badge records show exactly four colleagues in the building that night — and Marsh's desk calendar lists the same four names, each summoned to a private meeting at a time written in his own hand. The last name is crossed out.
At nine that morning, the audit was due before the board. The draft in the printer tray is missing its appendix, and all four insist their meeting was routine. Somewhere between the badge logs, the calendar and the missing pages, one late-night conversation ended with the trophy coming off its shelf.
Chief Financial Officer, Verent Capital
Forty-seven, meticulous, and the last founder-era executive who still read every number himself. Marsh spent three weeks building the audit alone, telling the board only that it would "correct the record." He booked the four meetings in ink, an hour apart — and told his assistant to confirm none of them.
Chief executive and co-founder
He staked the firm's future on an acquisition that closes Friday — a deal Marsh's audit could sink. Pierce met Marsh at ten, left at ten-forty, and told the lobby desk not to log his return. He maintains there was no return to log.
Head of compliance
Half the sign-offs the audit questions carry her signature, though she says she signed what she was given. Her badge entered the thirty-fourth floor twice that night. Reyes accounts for the first swipe, at 11:05 — and denies the second ever happened.
Head of trading
The audit traces a quarter of quiet losses to her book — a "timing difference," she calls it. At 12:15 the stairwell camera caught her between floors, though the elevators were running. She says she needed air. The stairwell has no windows.
Senior analyst
Marsh's protégé, first in every morning and last out every night — and the models behind the questioned numbers are his. His workstation shows a twenty-five-minute gap in activity around midnight. Cole says he was at his desk the whole time, thinking.

UNSOLVED
The killer's identity is sealed inside the case engine — it is generated live when your investigation begins, and no two investigations unfold the same way. The only path to the truth runs through the interrogation room.
