Michael Moorcock’s first professional standalone publication, written in collaboration with James Cawthorn, it was No. 501 in the Sexton Blake Library, “‘the longest running detective series in the world’; his adventures had started in 1889”. ‘Desmond Reid’ was a house pseudonym, used this one time only by either writer. Intended by them “to be the ultimate locked room mystery … [S.B.L. editors] Philip Cambers and Bill Baker had other ideas!”.
