A retired police chief is asked to help out In a murder investigation. I really enjoyed the set up of the main characters, retired police chief, living with a gay friend and working with the local police force on a consultancy basis. The reason I gave this four stars is because it would seem very unlikely that a civilian, albeit a retired police chief would be given such a free hand. Practically running the investigation on his own. Then when he finds peadophile  tapes he does not think this has much bearing on the case, but is looking for an unhappy house buyer??  The book is well written and I enjoyed it but came away a bit disappointed because of these points.
