SUMMARY: Agatha Christie's most ingenious murder mystery, reissued with a striking new cover designed to appeal to the latest generation of Agatha Christie fans and book lovers. The villagers of Chipping Cleghorn, including Jane Marple, are agog with curiosity over an advertisement in the local gazette which reads: 'A murder is announced and will take place on Friday October 29th, at Little Paddocks at 6.30 p.m.' A childish practical joke? Or a hoax intended to scare poor Letitia Blacklock? Unable to resist the mysterious invitation, a crowd begins to gather at Little Paddocks at the appointed time when, without warning, the lights go out!
