Three Seconds in the Dark

The automated system report confirms: The scheduled weekly test for the backup power generator was triggered at exactly 22:05:00, which necessarily caused a complete power outage across all the mansion's circuits for exactly 3 seconds before the power returned.

The internet-connected pacemaker implanted in the victim's chest sent a cardiac arrest signal (instant death) to the hospital server at exactly 22:05:02.

The magnetic lock on the office door is impossible to open from the outside; however, it is programmed with a fail-safe system that automatically opens the door for exactly 3 seconds during any power outage or fluctuation, then locks again. The door can always be opened from the inside with a mechanical handle.

The classic vinyl record player in the music room is entirely mechanical and has no backup battery. The manual states: 'If the power is cut while the record is spinning, the motor stops with violent braking while the needle remains pressed hard against the vinyl, inevitably causing a deep, permanent transverse scratch.' An inspection proved that the record currently on the player is perfectly intact and has no scratches whatsoever.

Wet footprints and damp house slippers were found leading directly from the basement spa to the victim's 'Bedroom' (which is a completely separate room in a different hallway than the office). The bedroom drawers were found open with papers scattered inside.
