With no village bobby in Aidensfield Tommy Unsworth and his motor biking friends seizes the opportunity to make a lot of trouble in the village. Even Aunt Peggy is upset that the bikers are trespassing on Lord Ashfordly's land upsetting the natural order of things by frightening the game away and leaving her traps empty. But when it will take a while to get at permanent replacement Miller organizes a stop gap. Thus PC Joe Mason moves to Aidensfield on a temporary basis while he awaits his transfer to the Met. Mason is very resourceful and a bit of a maverick, and his senior officers were more than happy to get rid of him. The villagers are not too crazy about him either. But Unsworth is not the only source of trouble around. A professional gang from Manchester is targeting country houses in the area stealing paintings, antiques and jewelery.
