Blue-Eyed Devil by Robert B Parker

Virgil Cole and Everett Hitch are back in Appaloosa, keeping peace at the Boston House. Chief of Police Amos Callico has political aspirations and a force of 12 men to keep peace in the town (if the business owners pay their dues, that is... ). One evening General Laird's son was in the bar being drunk and disorderly and Virgil and Everett had to take charge, with the boy getting killed. Parker has written another chapter in this saga of western justice, political intrigue, and the life of a gunman. Parker fans will love this, I did. Sandy Penton
