Detective Chief Inspector is a rank with its own gravity in British crime fiction, and putting it on the cover sets expectations at once: procedure, hierarchy, a case that has to be built rather than solved by intuition. JJ Richards writes DCI Walker, and our catalogue holds the first three cases bound together as a single collection.
The shape of that collection is informative. A trio of cases inside nine hours means brisk, tightly plotted instalments rather than sprawling doorstops, the sort of crime writing that keeps its focus on the investigation and trusts the listener to keep up. It is a discipline that suits serial detective fiction, where the pleasure comes from watching a familiar method applied to unfamiliar trouble.
