TVC 666.6: David Koenig, author of Shooting Columbo: The Lives and Deaths of TV's Rumpled Detective and Unshot Columbo: Cracking the Cases That Never Got Filmed, talks to Ed about "Fear No Murder," an innovative mystery that Peter Falk not only wanted to film, but which would've served as the coda to the Columbo series, were it not for an impasse between Falk and ABC over casting that ultimately killed the project. Both Shooting Columbo and Unshot Columbo are available through Bonaventure Press.
