William has a good, steady job in retail. He works in the bedlinen department of an Oxford Street store. He knows everything there is to know about comfy.

Lucy has a portfolio career which, in her view, is no kind of career at all. Her life is a mess, her love life even more unsatisfactory than that. She wouldn’t be comfortable if she sat on a sofa in Heal’s. Unable to sleep, she thinks a new pillow might be the answer.

William and Lucy are not connected. Yet the pair of them share a terrible memory from the past, the sort of joint recollection that changes with the light, depending on who you were and where you were standing at the time.

The question is: what to do with it?
