Tony Petrocelli is an Italian-American, Harvard-educated lawyer who grew up in South Boston and gave up the big money and frenetic pace of major-metropolitan life to practice in a sleepy city in Arizona named San Remo. His wife Maggie and he live in a house trailer in the country while waiting for their new home to be built. Tony drives an old pickup truck, always a little too fast. Petrocelli hired Pete Ritter, a local cowboy and ex-cop, as his investigator.
