The book cover is black, with the title and author's name in white writing at the top, and the publisher's logo at the bottom. Below the title is an image of room with light coming in through windows and a large pair of glass doors, which are thrown open, on the right-hand side. On the left is a short flight of stairs leading to another room. The warm colour and low angle of the light suggest it is early morning or evening. The room inside is lit up but the small square frames on the doors and windows cast long shadows. You can glimpse trees outside the window. The room is unfurnished, with a brown carpet, white ceiling tiles and long strip lights, which are turned off. The photograph is of a large room -possibly a day room -in the West Sussex County Asylum, later known as Graylingwell Hospital, which closed in 2003. The photographs were taken in 2017 by two (anonymous) brothers, whose website, The Time Chamber (https:// the time cham ber.co.uk/ ), documents empty and derelict buildings, including many former asylums.
