Old Flame - S16.E21

Santini tries to convince his lover, Jess Orton, to set him up with some drug dealers – he wants out of Sun Hill, and DS Timpney, his friend in Area Drugs, has promised him a place in the squad if Santini can get him evidence on them. However, before he has the chance, the Ortons' club is firebombed, and Santini is shocked when one of the officers assigned by AMIP to investigate the explosion is his old nemesis, DS Rosie Fox. Fox is convinced that Santini is linked to the events in question, but her AMIP DCI, Richard Pallister, believes otherwise. When Santini manages to locate Jess Orton, he persuades her to make a false confession to bombing the club in order to gain the trust of the suspected drug dealers.
