Judas Horse is the second in this particular series, however, I read this as a stand alone without any difficulty. It reads like a police procedural and thriller. Detective Jack Warr is invited to help with the local investigators based on his past success and reputation. He's able to build a tentative partnership with the local investigators despite his unorthodox methods and a few feathers he manages to ruffle. You root for Detective Jack Warr and his team to solve the crime spree happening in this charming English town pronto! What started as jewelry heists among the rich often covered by insurance, escalates to murder of some folks caught in the crossfire and the novel's pacing speeds up to match that urgency. Warr's able to infiltrate the crime ring by grooming a 'Judas Horse' so that hopefully she can lead him to figure out who the unsavory characters are before they commit another violent crime.
