S15·E23 On The Road

Lennox and Rawton go to Salisbury to bring in a con-man, George Riordian, for questioning, but he proves to be a slippery customer when he first gives them the slip at a service station, and then later on absconds altogether when the car they are travelling in breaks down and Lennox has to pull over to repair it. The pair manage to find a missing £50,000 which Riordian supposedly stole from one of his victims, Stella Kauffman, but then Riordian appears at the station the following day to hand himself in. When Kauffman then announces she is withdrawing the charges against Riordian, Lennox realises that the whole incident has been a con from the start and that he and Rawton have been had.
