Jim Dempsey was one of New York's finest. A tough, street-wise cop - a man who couldn't be brought. But when a corruption scandal hit the force Dempsey was left out on a limb. That's how he found himself in England, waiting for things to cool down and clashing with the beautiful Harriet Makepeace, Cambridge graduate daughter of an English Lord and chasing a high-flying career at Scotland Yard. Holding them together is their boss, Gordon Spikings, irascible head of SI-10 and not a man to be trifled with. Dempsey and Makepeace may seem like an unlikely duo but together they're dynamite!
