A Touch of Frost

DI Frost is called to the scene of a kidnapping where the driver and conductor of a Denton bus have been captured and hidden away in what turns out to be a revenge plot on the part of two people whose relatives were killed when a lorry driver ploughed into a bus queue a few years before - simultaneously, Frost is investigating a series of credit card thefts and the mysterious death of children's entertainer Charlie the Chuckling Clown in the backstreets of Denton. As the main plot gathers momentum, Frost, Toolan and DS Drake race against the clock in an attempt to rescue the kidnap victims before it's too late.
