 Malcolm Fairchild has just had his car checked and MOT-tested at Bernie s garage when he loses control over the vehicle and plunges into a garden. Luckily nobody gets seriously hurt, but Bernie gets into serious trouble because the tyres are bold. The next morning he is nowhere to be found and David fears the worst.. Helen Trent s estranged husband finds out about her affair with Rob Walker and makes a complaint to Sergeant Miller, who takes the matter very seriously.
