Be Kind to the Killer

Be Kind to the Killer is a 1952 detective novel by the British writer Henry Wade. As with many of his works it is written in the style of a police procedural.
A review by Julian Symons in the Times Literary Supplement observed that "Mr. Wade’s writing is pedestrian and at times faintly comic" although concluded "But Be Kind to the Killer is a sound piece of work, which contains some interesting details of police procedure."
