It's Murder. But Is It Art? (1972)

It's Murder. But Is It Art? is a 1976 six-part comedy thriller serial written by David Pursall and Jack Seddon, and produced for BBC One. It stars Arthur Lowe, John Gower, Dudley Foster, Arthur Howard, and Anthony Sagar.

Eccentric artist-turned-detective called Phineas Drake investigates when beautiful blonde Tina Kent is discovered murdered in the drawing-room of Brigadier Austin Binghop. Insp. Hook is convinced that Binghop is the culprit and takes him into custody. However, Mr Drake thinks otherwise and places himself in considerable personal jeopardy – with the trail leading him to the house of Chelsea socialite Mrs MacPherson.

Barring some low-quality, off-air recorded monochrome trailers from the time, the entire series is believed to be lost.
