From The Perry Mason TV Show Book (Revised)
Sixties heartthrob David (The Man from U.N.C.L.E.) McCallum plays Phillipe, a Frenchman who has fallen for a married woman. She gets him to bankroll her separation from her violently abusive husband, but Phillipe learns later that the husband took the money to buy into a ski resort deal. Phillipe tries to confront the cad on the slopes but is unsuccessful, and despondently returns to Los Angeles. The husband is not so lucky: He’s killed when his plane crashes. Seems his blood was loaded with barbiturates. When the police suspect that the Frenchman doctored the coffee in the dead man’s thermos, Phillipe finally smartens up and gets Perry as his lawyer.
