Boomerang

The only way Ted Hogwood can get his guitar out of hock is to accept an assignment from the AABC, a not nearly official branch of the US intelligence community. He is partnered with Jerry Kwiatkowski, master of the Hammond B-3 organ as well a talented picker of locks and hot-wiring to steal a boomerang containing secrets that should have died with J. Edgar Hoover. It would be simple if a crossbow wielding assassin, two unemployed Australian women of a certain age, the Director of US Intelligence, and a clothing optional former Onion Festival Queen weren't also on the trail. It would also help if they knew what they were doing.
