Harry Bosch Wiki

"Jumpin'" John Brooks (b. 1 July 1954; d. 30 Oct 1993) was a detective with the Chicago Police Department, the partner of Lawrence Washington, and the husband of Edna Brooks.

In 1993, Brooks investigated the murder of 12-year-old Bobby Smathers, but failed to arrest a suspect and became obsessed with the case. He eventually sought counseling with Dr. Ronald Cantor, and began making emotional and psychological progress.

Brooks was murdered by the serial killer known as "the Poet" on 30 October 1993 in such a way that his death appeared to be a suicide, and the phrase "through the pale door" – a line from the poem "the Haunted Palace" in Edgar Allan Poe's story "The Fall of the House of Usher" – was found at the scene.
