If the chaise longue, Chinese screen, mismatched side tables and collection of ceramic fruit bowls that I found under the sheets weren’t enough of a clue, I also found an easel and a box full of squirrel-hair paint brushes gone rigid with disuse. Somebody had used the rooms as a studio, judging from the empty beer bottles neatly lined up against the south wall. Probably apprentices like me – that, or a wizard with a serious alcohol problem.

Stacked in the corner and carefully wrapped in brown paper and string were a series of canvases, painted in oils. These included a number of still lives, a rather amateurish portrait of a young woman whose discomfort was palpable, despite the sloppy execution. The next was much more professional – an Edwardian gentleman reclining in the same wickerwork chair I’d found under a dust sheet earlier. The man was holding a silver-topped cane and for a moment I thought he might be Nightingale, but the man was older and his eyes were an intense blue. Nightingale senior, perhaps? The next, probably by the same painter, was a nude with a subject that so shocked me I took it to the skylight to get a better look. I hadn’t made a mistake. There was Molly, reclining pale and naked on the chaise longue, staring out of the canvas with heavy-lidded eyes, one hand dipping into a bowl of cherries placed on a table by her side. At least, I hope they were cherries. The painting was in the impressionist style so the brush strokes were bold, making it hard to tell: they were definitely small and red, the same colour as Molly’s lips.

I carefully rewrapped the paintings and put them back where I’d found them. I did a cursory check of the room for damp, dry rot and whatever it is that makes wooden beams crumbly and dangerous. I found that there was still a shuttered loading door at the courtyard end of the room and mounted above it, a hoisting beam. Presumably to serve a hayloft for the coach horses.

As I leaned out to check it was still solid, I saw Molly’s pale face in one of the upper windows. I didn’t know what I found stranger, that somebody had persuaded her to get her kit off, or that she hadn’t changed in appearance in the last seventy years. She withdrew without apparently seeing me. I turned and looked around the room.

This, I thought, will do nicely.
