Jumping Jenny
by Anthony Berkeley (Hodder & Stoughton, 1933)
audiobook read by Seán Barrett (Soundings, 2022)
Musing upon what looks to be a house-party suicide, prominent amateur detective Roger Sheringham, present from the outset, indulges one fancy too many and accidentally implicates himself as prime suspect in a murder! A droll study in dramatic irony and narrative doctoring.
