"A very enjoyable addition to this addictive series."
It is March in Bruncliffe, in the Yorkshire Dales. Though winter hasn't yet completely loosened its grip, things should be looking up. But they're not. Samson O'Brien of the Dales Detective Agency is being questioned about a murder, and his time as an undercover policeman with the National Crime Agency in London, and his subsequent suspension from the force could be exposed. Not only that, his partner in the Dales Detective Agency, Delilah Metcalfe, now appears to have given up on him. Then, in the school locker of Nathan, Delilah's nephew, a small tin filled with ketamine (a class B drug, banned in the UK), is discovered. Is Nathan doing drugs? He denies he had anything to do with it, and when no one believes him he runs away onto the moors. As Samson isn't liked in Bruncliffe, suspicion falls on him as being the dealer. But that's not the end of the troubles that are besetting Bruncliffe. Someone is poisoning dogs in the town, laying tainted sausages at various points so that the dogs will eat them. Herriot Ellison, the local vet, is worried that a dog may eventually die. Who could be doing this, and why?
Samson, meanwhile, has to attend a hearing in London about his case. Should he attend, or should he join the search party out on the moors looking for Nathan, and possibly jeopardise his career? Everything is finally resolved, though some important issues still hang in the air, no doubt being resolved in the next Bruncliffe book.
