Ross of the Yard. - Book 1, A copper in post WW11 London, #1

Post WW11, London was a dangerous place. It signaled the rise of the gangs, starting with the Maltese imigrants, who specialised in girls, pornography and strip clubs. But within a very short time, numerous gangs sprang up all over London. The police felt that they were fighting a losing battle, and they realised that they had to regain control of the streets and stem the crime wave. Murders were a daily occurence, and guns were in frequent use by hardened criminals. This book covers the efforts of one Detective Chief Inspector Ross and his Sergeant, Alf Morris, as they fight to solve murders.
And attempt to restore order to the streets.
