Synopsis by Hal Erickson
As made obvious by its title, this TV movie was an attempt to revive the once-popular private eye series Cannon, which ran from 1971 to 1976. Emerging from self-imposed retirement, corpulent gumshoe Frank Cannon (William Conrad) investigates the death of an old friend who formely worked for the CIA. Officially, the death has been ruled a suicide, but Cannon, as usual, has his doubts. Also mixed up in the intrigue is Cannon's former sweetheart and a Hughes-like millionaire. First telecast November 1, 1980 on CBS, The Return of Frank Cannon did not result in a weekly series, but William Conrad was able to find solace in his starring role on the subsequent weekly Nero Wolfe.
