As he awaits his anticipated promotion, Police Constable Rhea continues his work on the Yorkshire moorland beat of Aidensfield, reminiscing about his childhood in a similar idyllic village and making the inevitable comparisons. There is little doubt his rural upbringing helps him deal with the variety of incidents and people he encounters, such as a press photographer who gets lost while trying to locate a centenarian, a party of day-trippers who get imprisoned in a field and a farmer whose vehicles smother the lanes with mud. Constable Nick encounters psychic cows, ghostly racehorses and clever sheepdogs as he deals with a hoard of silver in the thatched roof of a cottage and the disappearance of a lad who has gone to climb in the Himalayas. Should Nick spoil his family's Christmas Day by going to inspect an empty car in a field? And how does he cope with a family who have acquired a little boy when no one knows who he is or where he's come from? It's all in the line of duty for Constable Nick.
