Alternative cover edition of ISBN 0141188340 Lise is thin, neither good-looking nor bad-looking. One day she walks out of her office, acquires a gaudy new outfit, adopts a girlier tone of voice, and heads to the airport to fly south. On the plane she takes a seat between two men.

Dame Lettie Colston is the first of her circle to receive these anonymous calls, and she does not wish to be reminded.

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.
