In the novel Murder is Easy, Jim Harvey is a mechanic who worked at Pipwell's Garage in the village of Wychwood under Ashe. He is the boyfriend of Amy Gibbs and they were, according to Mr Ellsworthy inclined to quarrel. Other vilagers, however, thought of him as a "most steady, superior young man".
Luke Fitzwilliam crossed him off his list of plausible suspects for the serial killer in the village. Amy Gibb had been killed by someone who planned in advance to get her out of the way and then made it look like an accident. Luke could not imagine Jim doing that. Secondly, he did not kill Lavinia Pinkerton as he was in the village on Derby Day. He had tried to get a day off but his boss refused because the garage had too much work.
