The Bookhouse Boys (formerly Citizens Brigade) were a secret society formed to combat the darkness surrounding the town of Twin Peaks.
The members, some of whom belonged to the Twin Peaks Sheriff's Department, also played a kind of vigilante role against drug dealers, etc.
Following an enlistment surge in the town brought about by a screening of the film 49th Parallel, the Citizens Brigade was formed in the 1940s to defend Twin Peaks prior to the United States' entry into World War II. Among the founders was Sheriff Frederick Truman, whose sons Frank and Harry would succeed him as sheriff and become members of the Bookhouse Boys, by which name the group eventually began to be known.
While not initially aware of the existence of the Black and White Lodges, the Bookhouse Boys had long known that there was a kind of evil surrounding the town which caused dark and unusual events to occur. They believed that this might be part of the "price" the town had to pay for all the benefits that came from its comparative seclusion from the modern world.
The best-known members of the Bookhouse Boys were:
- Sheriff Frederick Truman (founder)
- Sheriff Harry S. Truman
- Deputy Tommy "Hawk" Hill
- "Big" Ed Hurley
- James Hurley
- Joey Paulson
- FBI Special Agent Dale Cooper, made an honorary member; the only known non-resident member.
- Frank Truman
- Andy Brennan
- Hank Jennings was also once one of the Bookhouse Boys, and in fact, "one of the best" according to Harry Truman. However, Hank's later behavior, including drug dealing and assassination attempts, which resulted in him getting sent to prison, suggests that he was almost certainly expelled.
- Jerry Horne
The seven members of the starting lineup of the 1968 Twin Peaks High Lumberjacks were all in the Bookhouse Boys.
Lucy Moran bought the books for the organization.
