Hour Four: the lights
Nudge. Each light belongs to one of your nights in this house. Work out which century each came from, then put out the newest first.
Harder
The house lights are 2026, the wireless set is the school's in 1942, the red lamp is Mrs Marsh's in 1922, and the kitchen fire is the one you kept in 1665. Newest first.
The hour, in words
Four buttons in a row: The house lights, The wireless set, The red lamp and The kitchen fire. Tap them in the order you would put them out; each tap is added to the line marked Put out so far. Then tap Put them out. Start again clears the line.
The answer
The answer is house-set-lamp-fire.
Newest first and oldest last: the house lights (2026), the wireless set (1942), the red lamp (1922), and the kitchen fire (1665) last of all, as she asked.
