Craig Stevens plays Gunn, Pete to his friends, a handsome, suave detective tough enough to take on the hardest of hard cases, but a soft touch when it comes to the ladies. His girlfriend, the gorgeous singer Edie Hart (Lola Albright) is the featured singer at 'Mother's,' a smoke-filled jazz club used by Gunn as his unofficial office. Other regulars at the club include a colorful cast of musicians, pool hustlers, artists and a sculptor. His standard fee is $1,000.00, and his reputation keeps the customers lined up for his services, sometimes referred by Mother (Hope Emerson, season one; Minerva Urecal, seasons two and three), or his police buddy Lt. Jacoby (Herschel Bernardi). A man with expensive tastes, Peter Gunn drives a stylish two-tone Plymouth Fury Convertible, equipped with a mobile phone!
