Holmes investigates a suspected money-launderer named Terry Jowit, who is wanted by police in Scotland. Holmes discovers a cheque in Jowit's mail from an antiques dealer, which leads her to suspect that he buys expensive antiques with 'dirty money' as a means of laundering it. What Holmes doesn't count on is antique dealer Judy Ryan having a tape of Beech accepting a bribe from herself and Jowit, and Beech willing to do anything to keep it a secret. However when Holmes confronts Beech, he threatens her with the evidence that she has illegally opened Jowit's mail. When Judy Ryan is later victim in a hit-and-run, Beech uses the opportunity to fit Jowit up – but he finds himself unsuspecting when Jowit tells Holmes' about his dodgy dealings, leaving the corrupt DS scrambling to cover himself.
