Nessuno è colpevole. Un'indagine di Arthur Jelling

In this third novel of the series, Detective Arthur Jelling is faced with an unexpected case when a man confesses to accidentally shooting and killing his friend during a hunting trip near the Canadian border. The man had wandered for two days before finally presenting himself at the Boston Police Department, where he confesses not only to the accidental homicide but also to an old grudge against his now-deceased friend, Ted. Jelling, known for his sharp logic and deductive reasoning skills, is convinced that "if the data is sufficient, any problem can be solved." In this case, however, Jelling must delve deeper into the psychological motivations of the parties involved to uncover the truth behind the seemingly straightforward incident.
