Murder Unmourned — George Douglas

When Carl Slesser, organiser of big-time crime, moves into the area, the North Regional Crime Squad know they'll have to keep a close eye on him. But Slesser joins forces with James Barton, an insurance surveyor who has ambitions to use his professional knowledge for his own ends. Then comes the Big Operation. Detective Constable Norwood patiently tries to uncover a lead to bring the two crooks to book. He finds it - but only after staring death in the face.
