Murphy's Law

Working undercover as a gun dealer, DS Tommy Murphy changes course in the middle of a sting operation when a buyer, Caz Miller, mentions that the gun is to be used for a hit.

DS Tommy Murphy continues to work undercover building the case against Dave Callard. Caz Miller arranges for Murphy to meet the McGeechan brothers who want their automatic weapons to be re-activated.

Still undercover to bring down Dave Callard, Murphy works as an intermediary when he learns there's a deal for a large sum of counterfeit money.

Murphy begins to realise how big this case is. His life really does depend on it.

Heroin from Afghanistan needs stopping, but events take a turn for the worse.

Callard is systematically destroying the forensic evidence against him. After so long investigating, Murphy can't blow it now, and has to act fast.
