Dangerous Davies is on the trail of the killer of an Albanian refugee, and his search leads him to a dating agency – where one of the clients is someone he knows only too well.

Davies makes a gruesome discovery when he is called in to settle a dispute between neighbours over a leylandii hedge. The hapless detective is then called away to deal with a suspected suicide.

Davies is called in to investigate the suspicious death of wealthy artist Maurice Leyman, found dead after a fire in the studio in the garden of his luxury home. His wife is rather calm about the whole thing and has a dodgy alibi, but Dangerous is reluctant to point the finger at her.

Davies decides to toughen up after falling victim to a cruel practical joke by colleagues Barrett and Pimlott. He is then dispatched to investigate the death of a medical researcher. It looks like suicide, but Davies is convinced it's murder.
