Trunk Music is the sixth novel by American crime author Michael Connelly,[1] and the fifth featuring the Los Angeles detective Hieronymus "Harry" Bosch.

After the name and address of the victim are discovered, Harry and one of his team goes to interview the wife.

The team later finds out that a branch of LAPD had placed bugs on the victim's phone without authorization.

Bosch sees video of the poker game the victim was in, and he recognizes one of the other players as a former FBI agent with whom he had an intimate relationship, Eleanor Wish.

Fingerprints from the murder victim's leather jacket match those of Luke "Lucky" Goshen, top aide to the Las Vegas mob boss Joseph "Marks" Marconi.
