While Denton´s female population has to watch out for a con man posing as Frost, Frost himself has more dire concerns: a woman found dead by the railroad. To top it off, Frost has to work with a soon-to-be wash-out with possible drug problems. Then a disliked surgeon goes missing, and turns up dead.

With the railroad murder solved, Frost tries to come to terms with having an previously unknown daughter. Detective Reid is sent to look for contraband cigarettes, but is found nearly dead on a public toilet. Was he high, or did Frost´s lookalike have anything to do with it? Meanwhile, Frost eliminates suspect after suspect in the surgeon murder, and ends up saving several lives.

A body with no identification is found in a local reservoir, and a couple fall victim to a brutal killer in their own home. Frost is assigned a new, female, West Indian detective constable, Ronni Lonnegan, and gets off to a bad start with a few racially-insensitive remarks. He then reluctantly accepts the help of a psychological profiler, psychiatrist Pam Hartley, who he met at a conference. Meanwhile, there is an inspection of Denton Police underway, and Frost's old-fashioned methods are not endearing him to the inspector, so Supt Mullett is forced to give him more support than usual.

Background enquiries turn up two previous deaths, which appear related to the case. But their initial suspect, armed bank-robber Charlie Lehman, turns out to have died in prison over a year earlier. As they work to profile the killer they are hunting, Frost starts to get close to Hartley personally as well as professionally, though neither realises just how closely she is linked to the case until it is almost too late. Frost has a race against time to find where she is being held.

After a seven-month long suspension, Frost is back on the job. His first case is a floater in Denton River, with £6000 in his pockets. The man also carries with him a list with four sets of mysterious numbers, and the keys to two different cars. The local dance competion is the venue for another drama: a missing con man who recently switched dance partner, and a woman with a Hollywood name and a terrible temper - who keeps on ordering new fridges for her dance partners... But Frost is more interested in getting his teeth back in order after a particularly vicious lollipop.
