The Smoke before the Alarm

Hard · A municipal archive

Smoke sends staff outside and a register disappears. An alarm timestamp seems to unite the events. Determine whether the theft preceded the smoke and who agreed to which act.

Investigate this case

Read the case file below, or open the interactive desk to examine records, keep notes and submit your reasoning. These are the case materials, without the solution.

The scene

There is no fire damage or injury. The supplied inspection identifies harmless theatrical smoke and a separately removed register. All staff leave through the supervised exit.

Case records

Read each record on its own terms. A claim made by a person is different from a fact established by an independent record.

Case record · Event room

Private cue agreement

Vera and Sam agree to stage an unauthorised alarm to obtain dramatic promotional footage. Their stated plan names no register or archive access.

Case record · Event room

Smoke examination

The smoke originates in Vera’s demonstration unit. No burning archive material or accidental fire source is found.

Case record · Control desk

Alarm reference log

The alarm first sounds at 15:40, twenty-five minutes after the sealed cart leaves. It cannot date the removal to evacuation.

Case record · Copy desk

Buyer’s complete exchange

Before the copy job Jonah offers Esme the bound original; Esme agrees to a private payment and asks that it travel as waste.

Case record · Service yard

Waste-cart inspection

The original register, matching its bound accession, is hidden below paper in Jonah’s sealed waste cart dispatched at 15:15.

Case record · Control desk

Cancellation and acknowledgment

Vera and Sam both acknowledge that the smoke demonstration approval was withdrawn. Sam nevertheless grants Vera the private test interval.

Case record · Control desk

Separate message and movement audit

The complete preserved exchanges show no contact between the register agreement and smoke agreement. Vera and Sam remain in the event room throughout the copy and cart interval.

Case record · Archive

Register shelf and job record

The register is present at 15:00, handed exclusively to Jonah for a copy job at 15:05, and not returned at the job’s 15:12 completion.
