How to investigate
Read the evidence, compare accounts and discuss your theories. One of the five suspects acted alone: no accomplices or supernatural tricks. Investigator-verified records are accurate and complete for their stated intervals; suspects may be mistaken or dishonest. All times use the same museum clock.
Use hints freely and revisit any evidence you've opened. Everything you need is in the case. Progress lasts while this page stays open; refreshing starts over.
EVIDENCE 01
The interruption
Time (PM)
Verified event
8:17:00
Gallery display power fails. Emergency lighting, cameras and access alarms stay powered.
8:18:27
Lighting returns. The upper display looks empty.
8:19
Celia stops departures and requests an inspection.
Neither access door opened during the interruption. No unauthorized-access alarm sounded.
Everyone has an explanation.
Five people worked around the exhibit before the reception.
The Curator
Celia March
Read statement
“The case was checked and secure. We are very particular about security. And fingerprints.”
The Security Engineer
Dev Mercer
Read statement
“I checked the mechanism before the reception. At 7:57, I checked the outside seal and alarm again. I didn’t open the case.”
The Restoration Expert
Rowan Vale
Read statement
“I returned the real stone to its mount. Ask anyone where I was when the lights went out.”
The Journalist
Jules Finch
Read statement
“I photographed the display at 8:10. There was definitely a blue stone in it.”
The Guest Illusionist
Milo Penn
Read statement
“My jewels are foam. The budget stretches further when the diamonds are washable.”
EVIDENCE 03
The press photograph
Jules Finch · Press photograph
The upper display, seven minutes before the interruption.
8:10 PM: Jules’s photograph shows a blue stone in the upper display. It is clear enough to prove an object was present, but not detailed enough to identify its internal marks.
What does this establish—and what does it leave unanswered?
Same color. Different identity.
EVIDENCE 02
The inspection records
The two stones share a shape and color. Compare their internal marks against the museum’s reference cards.

Need a hint?
Match the positively recorded marks to the references, then compare the inspection times with 8:17.

Real at 7:50; demonstration stone at 7:56. The substitution happened before the blackout.

Verified room occupancy

Select a room to see who was there from 7:52–7:56 PM. This exhibit room was secured for preparation before guests were admitted. Plan not to scale.
Choose a room above.
Continuous footage verifies identities and locations. Nobody enters, exits or passes objects into the preparation room during Rowan’s occupancy. The case is reachable only from that room during maintenance; there is no other transfer opening.

Who could reach the case while the real stone was exchanged?
A locked case can still change.
EVIDENCE 04
The instruction card
BELLWEATHER MUSEUM · DISPLAY EQUIPMENT
Automatic protection tray
STAFF INSTRUCTIONS
SECTION VIEWPOWER ON
Cutaway for clarity. The tray moves inside the closed cabinet.
Power interruptionThe battery-powered mechanism lowers the tray into the base.
Power restoredThe tray stays latched down. It does not rise automatically.
Manual resetOnce power is restored, staff reset the mechanism to raise the tray.
The tray is raised. Try cutting the display power.
Alarm behavior
Access doors are monitored. Normal tray movement does not trigger the access alarm. The compartment has no other exit.
EVIDENCE 07
The controller audit
Time (PM)
Verified controller record
7:49
Dev finishes diagnostics. No interruption is scheduled.
7:55:12
A command is entered at the preparation-room console: interrupt display power at 8:17 for 87 seconds.
8:17:00–8:18:27
Scheduled interruption executes.
Commands can only be entered at that local console. The complete audit confirms direct entry at 7:55:12, no earlier queued insertion, no remote scheduling and no later edits.
Need a hint?
Does restoring power raise the tray, or does that require a separate reset?
Show explanation and continue
Interruption begins → tray lowers → lights return → tray stays down. The stone should be inside the locked base.
Check the remaining evidence.
EVIDENCE 09
The base inspection
BELLWEATHER MUSEUM · INVESTIGATOR RECORD8:23 PM
The investigator opened the service door at 8:23. The stone remained on the lowered tray.
IDENTIFICATION CHECK
Recovered stone
Compare its mark with the museum’s reference. The access seal was intact until the investigator opened the compartment.
8:23 PM: The investigator finds the demonstration stone on the lowered tray inside the base. Its bubble-and-tail mark matches the reference. The compartment’s seal was intact until the inspection.

None opened the case. Milo’s suspiciously labeled “DISAPPEARING JEWELS” pouch contains foam props. Dev’s name on the controller identifies its installer, not who last used it.
EVIDENCE 10
A promised delivery
A prospective buyer supplied this authenticated message from Rowan:
“I can deliver the real Starfall Sapphire after tonight’s reception. The agreed payment will clear the workshop’s outstanding debts. I’ll bring it in my restoration transit box.”
The buyer expected an authorized sale. The museum had authorized neither a sale nor removal of the stone.
Three answers. One explanation.
You can revisit any evidence before answering. There is no penalty for reconsidering.

This reveals the full solution.
CASE CLOSED
The theft happened earlier.
THE RESTORATION EXPERT
Rowan Vale
Exchange window: 7:52–7:56 PM
Rowan exchanged the stones during the 7:52–7:56 preparation window.
The genuine sapphire was verified at 7:50. The demo stone was present by 7:56. Only Rowan had access during the exchange window.
At 7:55:12, someone at the room’s local console scheduled the interruption. Rowan was alone there then, too.
At 8:17, the tray lowered the demo stone into the locked base. When the lights returned, the tray stayed down. No door opened. No unauthorized-access alarm needed to sound.
Rowan’s public blackout alibi was true. It was an alibi for the wrong time.
The promised sale explains the motive. After assembling the evidence, the investigator opened Rowan’s held transit box and recovered the real sapphire.
Why the others are cleared
Celia and Dev’s earlier access ended before the genuine-stone inspection. All four innocent suspects were elsewhere throughout the exchange window. Their jobs, props and photographs could not change that timeline.
Milo asked the investigator to record that a tray lowering itself was “furniture, not magic.”
The trick wasn’t stealing a sapphire in 87 seconds. It was making everyone investigate those 87 seconds.
