‘Remember you must die’ says the telephone caller. This is the message communicated in a series of anonymous calls made to many elderly people, including; Dame Lettie, a blue-blooded reformer, Godfrey, her rather irritating brother, and his once fabulous novelist wife, Charmian. But who is the caller? And why are they reminding them of this final truth? It’s unsettling and mysterious. The activity increases and soon a witch-hunt is in full force, with nobody beyond suspicion.

First published in 1959, Muriel Spark’s startling and timeless novel is at once a crime story, a black comedy and an important meditation on mortality.
