The Man in the Queue

"The Man in the Queue" is the first case for Scotland Yard Inspector Grant who was to become the hero of five of Josephine Tey's mystery novels. Josephine Tey was in fact a pseudonym for the Scottish author Elizabeth Mackintosh.
It is set in London and is concerned with a mysterious murder that is committed whilst people are queuing in front of the Woofington Theatre to see the final performance of Didn't You Know? starring Ray Marcable, the sensation of the moment.
Written over 80 years ago, in 1929, this crime novel has aged amazingly well and is mostly concerned with the personalities and motivations of the characters.
