Monthly Film Bulletin wrote: "The first of the Edgar Wallace series to employ one of his crime-and-Turf formats, this unpretentious little film makes good use of Jack Hedley’s engagingly diffident personality. Racing scenes occur only at the start and close of the story, which is otherwise unfolded with quiet slickness within betting circles and night-clubs."^[3]

Kine Weekly said "The picture revolves around the racecourse, but is a 'who-dunnit’ rather than a romance of the Turf. Jack Hedley has quite a way with him as Jim, Jacqueline Ellis is a pert Marion, and Patrick Magee and Harry Locke keep one guessing as Lucky Ben and Burnside. The supporting types, too, ring true. Night clubs scenes relieve the tension, the horse races exhilarate and what few loose strings there are are firmly tied at the finish."^[4]
