Murphy's Law

Murphy ends up being exposed and caught up in a vicious and final showdown between brothers Drew and Billy Johnstone.

Working deep under cover, Murphy manages to gain the trust of Billy Johnstone, while trying to uncover the associations between his brother Drew and a local Asian criminal network.

Murphy is called back to work after a leave of absence to be at his mother's side. His new job is to attempt to get close to Drew and Billy Johnstone, vicious Belfast criminals now operating in Leicester. Murphy thinks he's found himself a way in when a drug deal goes awry.

Callard starts systematically destroying the forensic evidence. Murphy and Miller fear that he may want to destroy one or both of them too.

The operation against Callard builds to its conclusion as Murphy is hired to help complete a shipment of Afghan heroin into England. His undercover work could help secure the conviction, but Murphy's presence is demanded elsewhere, as a key prosecution witness in the High Court.

After months spent trying to nail gangster Dave Callard, suddenly Murphy has a bigger fish to fry: a wealthy hotelier called George Garvey with a taste for ethnic art. Murphy bumps into someone to whom Garvey's son owes a lot of money and manages to get closer to Garvey. To forget the pressure during work he starts to drink. It looks like only Ellie can save him now.

Murphy tries to get counterfeit Euros for Callard, and asks fellow undercover officer Jill Calder for help. She has infiltrated an organisation that is printing the fake money. Together they try to set up a deal for both their clients and plan to make the big arrest during the handover.

Murphy finds himself before a disciplinary review board after having shot a suspect during an arrest and soon out of the force completely. He approaches psychologist Mark Maddison, who runs a support group for individuals who have have lost someone to violent crimes. In fact, Murphy is undercover as at least three suspects have been killed and all had some connection to a member of the group. However, Murphy's loyalties are torn when they provide him with the identity of the man who killed his daughter years earlier.

Murphy goes undercover in a convent when a young nun apparently commits suicide and a second vanishes. Posing as a priest, he finds any number of suspects. The older nuns obviously have a secret and are in league with a pharmaceutical firm. Murphy suspects they may be participating in illegal or unauthorised drug trials in their African mission.

Murphy goes undercover at a defence biotech contractor that may be covering up an industrial accident. Specifically, a young child is found to have drowned but the mother believes he died as a result of a chemical agent in the pond near where the child was playing. Despite being warned off the case, the police leave Murphy in place. When the family who helped the dead boy and his mother is executed, it becomes apparent that someone will stop at nothing to keep these secrets hidden.

Murphy finds himself going undercover with INTERPOL to smash a car smuggling ring run by Godfrey Raines with his son and daughter. Murphy manages to convince Raines that he too is a car thief specialising in high-end vehicles. He soon realizes that INTERPOL is after something else when they delay arresting Raines and start questioning about arms shipments. Into the picture comes former MI6–turned–criminal Mr Davidson.

Following a bungled attempt to close down an elaborate Russian crime-ring, Murphy and Guthrie find themselves embroiled in what appears to be a textbook crime of passion. An unknown blonde is busy murdering London's successful businesspeople. The only link is that all the victims are members of a state-of-the-art health club in the heart of the City.

In the glittering world of the West End club scene, the head of security of a well-known East End gang is found murdered. Prime suspect: gang leader Carl Tate.

The stakes are raised for Munday when his long-lost love and daughter reappear in his life.

Richard Mooney, London's most infamous kidnapper, is brought in, and the race is on for Murphy and Guthrie to get a confession in time to save his latest victim, Kate Jennings. To crack Mooney’s silence, Murphy is set up as a suspected terrorist and goes undercover into Bellview to befriend him. But when this master plan is unexpectedly threatened by the prison's very own protection racket, time seems to be running out for Kate.
