There was no mistaking the sound: it was that of a stealthy footfall, and it appeared to come from the staircase leading to the next floor.

Lord Bygrave left the Ministry on Friday evening, with plans for a fortnight's holiday in the country. But the following morning he had seemingly vanished into thin air. Now Scotland Yard are struggling to find evidence of foul play in the absence of tangible clues. A national newspaper is offering a reward for information about the Minister's disappearance - whether Bygrave be dead or alive.

Anthony "Algernon" Vereker, Lord Bygrave's friend and executor, joins Scotland Yard in their investigation of the mystery. So begins the first of five ingenious and effervescent detective novels featuring Vereker, an amiable and eccentric artist with a razor-sharp mind. Missing or Murdered (1929), is republished here for the first time in over 70 years. It includes a new introduction by crime fiction historian Curtis Evans.

'This is not only a detective story of considerable ingenuity, but it is also a well-written tale with good characterisation.' Times Literary Supplement
