Ernest Robertson Punshon (1872-1956) was an English playwright who created a series detective, graduate police officer Bobby Owen. He also wrote as H Robertson Halkett. ER Punshon is one of the most shamefully neglected writers of detective fiction. His ability to construct labyrinthine plots that keep the reader fascinated but not confused is rivalled only by John Dickson Carr, with whom he shares a powerful imagination, a gift of conveying atmosphere and setting, and a most ingeniously fertile mind, adept at devising clues and situations. Yet his work is not only exemplary detective fiction, but studies of character, of the catalyst that drives an ordinary human being to commit the ultimate crime. In their emphasis on bizarre psychology, fantastic (but logical and convincing) plots, and the ability of the past to influence the present (whether it be in the form of past crimes or literary or artistic treasures), his work resembles a combination of H.C. Bailey, Gladys Mitchell, G.K. Chesterton and Michael Innes.
