When Charlotte Rainsford, a retired schoolteacher, is accosted by a petty thief on a London street, the consequences ripple across the lives of acquaintances and strangers alike. A marriage unravels after an illicit love affair is revealed through an errant cell phone message; a posh yet financially strapped interior designer meets a business partner who might prove too good to be true; an old-guard historian tries to recapture his youthful vigor with an ill-conceived idea for a TV miniseries; and a middle-aged central European immigrant learns to speak English and reinvents his life with the assistance of some new friends.

In this engaging, utterly absorbing and brilliantly told novel, Penelope Lively shows us how one random event can cause marriages to fracture and heal themselves, opportunities to appear and disappear, lovers who might never have met to find each other and entire lives to become irrevocably changed.
