OBSERVE. DEDUCE. DISCOVER.
One rule. Infinite deductions.
Every suspect gives a partial account. Cross them until only one arrangement fits — exactly one person per row and per column. Whoever shared the victim's room becomes your prime suspect.
Observe
Read the floor plan — rooms, windows, doors and furniture, all seen from above.
Deduce
Cross-check the statements and rule out every impossible spot.
Discover
Locate all suspects; the empty seat reveals the victim — and the killer.
