Memento Mori

Dame Lettie Colston is the first of her circle to receive these anonymous calls, and she does not wish to be reminded. Nor do her friends and family—though they are constantly looking out for signs of decline in others, and change their wills on a weekly basis.

As the caller's activities become more widespread, soon a witch-hunt is in full cry, exposing past and present duplicities, self-deception, and blackmail. Nobody is above suspicion. Only a few, blessed with a sense of humour and the gift of faith, can guess at the caller's identity.
