Room 17

Smart Locks, a Secret Elopement, and the Suite Guests Request By Name

“Zero entries after 10:41 PM. Privacy Mode enabled from inside.”

All Cases

The Crime

Rowan Key, owner of the Rose Key boutique hotel, died in Room 17 — the suite her guests request by name. Smart-lock logs show zero entries after 10:41 PM. Privacy Mode, which disables housekeeping access and the corridor camera prompt, was enabled from inside the room. A secret elopement was planned for that same night to avoid press and investors. The next morning Rose Key's general manager had been instructed to quietly execute a sale of a controlling stake. Six people had reason to want the night to end differently: the security systems contractor who installed every lock in the building, Rowan's long-time partner, the general manager, the head chef, a travel-influencer guest in the room next door, and a loose connection to Rose Key's board. The logs all show zero entries. Someone who built the system decided which entries got logged.

The Setting

A boutique hotel in the soft-money register — burgundy wallpaper, brass sconces, wilted roses in crystal on hallway tables. Room 17 is the themed suite, the one the guests love, the one where quiet money books weekends away from their lives. The corridor stretches into shadow at both ends. A single heavy wooden door, number 17 in polished brass, is slightly ajar. Blue light spills out onto the carpet from a room that was supposed to have been empty until morning.

Suspects & Persons of Interest

CP
Celia Parksuspect
General Manager

Runs Rose Key’s day-to-day operations and vendor relationships. Under pressure from investors to keep occupancy high and incidents off record. Has motive to “manage narratives.”

DR

Controls the kitchen, the staff, and the after-hours liquor cage. Recently fought with Rowan over unpaid overtime and a threatened audit of kitchen books.

JK
June Kavanaghsuspect

A high-profile guest staying in Room 18. Claims she heard something at night. Publicly charming, privately demanding—her drama produces noise and distractions.

What You'll Investigate

TerminalV1

Smart-lock forensics — recover access logs, identify tampering patterns, and separate system events from human overrides.

How this technique works →
MetaScan

Photo and video metadata — guests, staff, and the contractor all left images that place them somewhere and something at specific times.

How this technique works →
NetTrace

Guest and staff communications — the elopement was planned somewhere; follow the thread.

Decryptex

Encrypted correspondence — the sale paperwork was sensitive, and the principals weren't careless enough to send it in plain text.

How It Plays

Expert difficulty. Approximately 120 minutes. Six suspects — the largest cast in any DetectiveOS case — means the interrogation network is the richest, with more statement cross-checking required than any other investigation. The central trick is the smart-lock layer: the logs are authoritative, except they aren't, and proving it requires understanding how the security system was installed and who maintained administrative access.

Frequently Asked

Around 120 minutes. Plan for a full evening, or split across two sittings.
Expert. Six suspects — the largest cast in DetectiveOS — makes the interrogation layer especially dense.
Yes, in the modern smart-lock variant. The door is sealed, Privacy Mode is active, and the logs say no one entered. Proving how someone did requires forensics, not theories.
Last Train is a classical locked-room; Room 17 is the smart-home version of the same puzzle. Different suspects, different tools, different motive (intimate partner / business partner rather than corporate whistleblower).
We recommend playing at least one Medium case first — The Vanishing or The Lighthouse Signal. Room 17 rewards patience with details.
