In Deep

A woman is found murdered in her flat in almost identical circumstances to one six months earlier. The victims have one thing in common – they are both members of the same Internet dating site. Kelly goes undercover and builds up a relationship online with prime suspect Dark Angel, but her tactics come close to entrapment. Liam's colourful love life threatens to compromise the operation when a spurned girlfriend starts to stalk him.

A group of anarchists kidnap the grandchildren of millionaire media mogul Clayton Waddington, but the family is adamant that the police should not be involved, thus avoiding a public scandal for their business. Liam and Garth are brought in under the guise of insurance company ransom negotiators and Kelly goes undercover living on the streets in an attempt to trace a homeless girl who has been linked to the scene of the abduction. Waddington agrees to the ransom demand, but tries to get the upper hand on the criminals by marking the cash. Garth is sent to deliver the money, but the kidnappers are smarter than anyone has realised and he finds his safety is severely compromised.

Police Chief DI Holland challenges gangster Charlie Pearce in order to regain control of a tough area of the city, but is shot dead on his way back from a public meeting with the area's residents. Pearce is, of course, the chief suspect. Liam, Garth and Kelly set themselves up as an operation selling expensive fake watches and it's not long before Pearce and his heavies call round for their first 'insurance' payment. Liam is embraced into Charlie Pearce's fold when, through a stroke of good fortune, he saves Pearce's life. Unfortunately Garth's unresolved issues with his brother Chris land him in deep trouble when Chris tracks him down and blows his cover. Liam's nerve is tested to the limit as he faces the choice of killing his partner Garth to prove his allegiance to Pearce, or coming clean and risking being killed himself.

Liam and Garth pose as drug dealers in a bid to capture Jamie Lamb, the country's biggest cocaine importer. They infiltrate his trusted entourage and fit in so well that when Lambs wife leaves him taking his two daughters with her, he asks Liam and Garth to kill her and bring back proof in exchange for a shipment of cocaine.

Liam infiltrates a white supremacist group which has begun a systematic petrol tanker bombing campaign. Garth is assigned to provide backup and support to Liam's family, but when a vengeful man - whose imprisonment Garth was responsible for - tracks him down, he finds instead that his presence is putting them in mortal danger.

Liam and Garth try to crack a paedophile ring which is operating through a sophisticated website. Liam befriends the wife of the webmaster and Garth goes undercover in prison to make contact with two of the principal players. After winning their confidence, he discovers that a grisly crime is about to be committed.

Garth goes undercover as a security consultant to track down Eva Richardson, the mind behind a powerful vice ring. He uncovers a link with the drug squad and, after one of Eva's girls is discovered dead in suspicious circumstances, an internal investigation is launched with results in Liam being posted back to investigate his old drug squad colleagues. In an attempt to infiltrate the web of corruption, Garth sets up a drugs deal. But when this goes disastrously wrong, it becomes clear that someone of high rank is playing for the opposition.
