In the early hours of the morning, a teenage female body is found face down in the marshland that runs along Southport's captivating coastline. Both Detectives Inspector Folkard and Sergeant Shakespeare strongly suspect secondary teacher Mr Rimmer to be their man. Mr Rimmer has many secrets; although he appears to live alone, he in fact does not. The closer Inspector Folkard and Sergeant Shakespeare get to their killer, the more they learn of Mr Rimmer's relationship with HIS MOTHER. It is only when Inspector Folkard looks back at similar attacks on young females that she begins to make some much needed headway. Inspector Folkard knows there is at least one other body close by; finding it could be the vital piece of the puzzle, but where to look?
