Serial killers all have unique profiles that help explain why they commit the heinous crimes they do. Dr. Alexander Gregory once worked as a profiler, helping to solve high visibility crimes. Until a tragedy brought him down. Now he works in a mental health facility that contains many such criminals. He just wants to understand why they do what they do.


Alex gets roped into helping local Garda to solve a murder in Ireland. He’s not sure he wants to do this again, but his ability to understand the minds of these criminals makes him the perfect choice. It’s not a paying job. And the local Garda are skeptical. When he has delivered a profile to them, they are able to focus more on the people who might be capable of such a heinous crime. 


There are costs to his own mental health, though, and he must confront his old demons along the way. Hopefully he will gather the loose threads and put them all together before another crime is committed.


Great procedural novel with some interesting twists. Alex Gregory is a charming and forthright profiler with his own secrets. The town of Ballyfinny sounds like a idyllic place until these crimes begin. LJ Ross has provided a very interesting tale of psychology, and its use in the field of police work. Thinking this might be a new series, and if so I’m in. 


Recommending for those who enjoy crime solving.
