Somebody has put a hook in the ceiling and it is empty.
It is a plain brass ceiling hook of the sort sold in hardware shops by the tray, a screw shank with a collar and a curl about the size of a thumb joint. It has darkened unevenly the way brass does. The curl catches the light along its outside edge and goes almost black inside the hook of it, and it throws one hard shadow down and to the right across the plaster.
It is screwed into the exact centre of the pale disc. Dead centre, between the two old screw holes, level with both of them. Whoever put it there sighted on the circle and used it.
That hook was not in the ceiling in the painting before this one. I painted that one from the ladder on a Tuesday and this one from the same ladder in the same position eleven days later, and in between somebody came into that room with a screwdriver and made a decision.
I have been staring at this cycle for ten weeks now looking for the moment a person does something, and this is it. Nine paintings of machinery working correctly with nobody attending to it, and then a hook. Not a repair. Not a replacement. Not compliance with anything. A person stood on something, chose the smoothest spot on a ruined ceiling, and installed a fixture that does not work at all unless a human being reaches up and hangs something on it and later reaches up and takes it down.
That is the opposite kind of object. The alarm was designed so that no one would ever have to think about it. The hook is designed so that it is useless until someone thinks about it. It has no battery, no signal, no maintenance schedule, and no opinion about smoke. It has a hole through the middle of the air where an intention is supposed to go.
Nothing is hanging on it.
I do not know what was meant to. A plant, most likely, or a lamp on a cord, or the sort of paper lantern people buy in the first month of a new tenancy. I asked two people in the building and neither of them knew who had done it, and one of them had not noticed it was there.
So the ceiling now holds three marks in a line. Two factory holes at a spacing decided in a factory, and between them one brass curl put in by hand, by somebody who wanted a thing in that particular place, and who has not yet come back with the thing.
The web is still hanging off the left edge of the circle. It was not disturbed. Whoever drilled into the centre of that disc did it without brushing the cobweb eight inches from their knuckles, which is either a great delicacy or a total absence of attention. I would like it to have been the first.
