Groucho Marx, secret agent

the long version

"It could be said that in this episode Groucho Marx operates as a Hollywood-style Scarlet Pimpernel, with a repertoire of outrageous puns covering the steely, daring life of a counterspy. But, as Groucho might retort, his cover is at the dry cleaner, and, besides, Groucho is not one to hide his light under any bushel (even one of stuffed clams). So he and Frank Denby, his sidekick, scriptwriter, and close friend, set out to uphold their reputation as amateur sleuths by looking into the death of British director Eric Olmstead."--Jacket.
