No sign of foul play'. So concludes Dr Carr's post-mortem on Agatha Dawson, and the case is closed. But Lord Peter Wimsey is not satisfied and, with no clues to work on, begins his own investigation. No clues, that is, until the sudden and senseless murder of Agatha's maid. Then the most debonair sleuth in detective fiction is faced with the problem of catching a desperate murderer before he himself becomes one of the victims...... and of discovering what goes on in the mysterious Mrs Forrest's Mayfair flat.
