Bank Holiday weekend. Beatrice Stubbs takes some holiday snaps on a secluded Welsh beach. Those innocent pictures reveal rather more than cliffs and seagulls, and someone wants them destroyed. But Beatrice has other things on her mind.
Assigned to the London Transport Police, she’s pursuing the Finsbury Park Flasher, trying to pre-empt a serious sexual offence. Meanwhile, neighbour Adrian and companion Matthew decide to play Poirot, and investigate the mystery of the disappearing photographs. Amateur detectives and professional criminals are a dangerous mix.
From deserted Pembrokeshire beaches, through the shadowy underpasses of North London, to the remote Irish countryside, Beatrice discovers the darker side of human nature.
