There are plenty of protagonists who are ex-cops turned PIs. On the other hand, there is but one former handler of police dogs who was forced off the force and now drives a truck delivering animal feed. Throw in a horsey atmosphere, a la Dick Francis, and you have the makings of a first-rate British mystery, which “No Going Back” certainly is.
Daniel Whelan, a ten-year veteran of the police force, was frozen out by his fellow workers after he disclosed detrimental information about the loss of evidence. He not only lost his job, but his marriage as well, and is also separated from his eight-year-old son. His only constant companion is Taz, a German shepherd retired as a police dog after being injured. Sort of a Rin Tin Tin and Lassie all rolled up into one, Taz is a super-dog in the grand tradition, and of course plays a major role in the novel.
