Alex Tanner is always on the lookout for work—mortgages on flats in Notting Hill do not come cheap, after all. So when TV producer Barty O'Neill mentions a particularly juicy assignment she jumps at the chance. Barty has been asked to investigate the shooting of Lord Sherwin, a famous society murder of the 1950s. Although suspicion quickly fell on Sherwin's beautiful wife Laura, the case has stubbornly remained unsolved. However Barty has a contact—Miss Potter, once governess to the Sherwin children—who is now ready to tell her story . . . And Alex is poised to uncover the truth behind a terrible secret kept hidden for more than 30 years.
