I was redecorating a holiday home for someone at the weekend - this place had been rented out to various tenants over the years and was in need of an overhaul.

There was a small, loose floorboard in one of the rooms; when I removed it, I found the note above, under a layer of dust and splinters. I took that picture of it, then put it back and replaced the floorboard.

(After digging a bit deeper, I’d found the present - five Milk Tray chocolates in a box. I didn’t risk it.)
