A ruthless Chinese crime syndicate has infiltrated Las Vegas. Heroin is on the rise in Sin City. So is murder. Sounds like a job for a trumpet player. Las Vegas, 1965. Hot off the heels of his last adventure in Cold War Copa, Trip Callaway, the young, wise-cracking musician with dreams as big as the Hoover Dam, has reluctantly agreed to go undercover and do some light spying for the government—light spying, as in report on who's hobnobbing with whom in the casinos along The Strip. But when Trip is asked to pose as a trumpet teacher to the thirteen-year-old step-son of a notorious crime boss, he quickly realizes he's agreed to more than he bargained for. Killers, prostitutes, heroin addicts and, of course, a beautiful woman, lead Trip into a deadly game of cat and mouse where he's not sure if he's the cat or the mouse. And, if that's not bad enough, the U.S. government has another surprise for him. From a ghost town in the Nevada desert, to the Pentagon in Washington, D.C., to the jungles of Vietnam, Trip Callaway must stay alive, sort it all out, and keep that famous Callaway cool in the process.
