This was an excellent "Inspector" cartoon, maybe the best one I've seen so far out of a dozen. It featured fantastic artwork and a fun story as our two guys - Inspector Clouseau and Deux-Deux - literally traverse the globe in search of a secret agent.
That "secret agent" has an important message to tell the Inspector, which could save his life. Each time the latter and his pal go to a city, something happens and they have to rendezvous somewhere else. Finally, they meet in a hut in the jungles of Naiorobi, only to find out the "agent" is a different kind of agent (who is a takeoff on British actor Terry Thomas, an actor who became well-known in the 1960s.)
It's on the DVD "The Pink Panther Classic Cartoon Collection, Vol. 6 - Inspector Cartoons." Note: June Foray did some quick voice-work in here as a Marlene Dietrich-type spy. Unfortunately, she only had one quick scene.
