This final Carter film is a lot of fun, with Nick (unwillingly, at first) taking on a ring of Fifth Columnists (since this was filmed before the US entered the war, we're not told the villains are Nazis, but it's pretty clear anyway). Of course, the helpful and persistent Bartholomew is at his side--much to Nick's irritation. To further complicate things--and to make them still funnier--Joyce Compton is along for the ride too, as a delightfully brainless "detective" named Christine Cross.

Joel & Garda Sloan, a husband and wife detective team, who also sell rare books in New York, take a vacation to Seaside City. At Seaside, Joel's pal, Mike Stevens is managing and preparing for their beauty pageant. Joel is made one of the judges plus he has invested $5,000 in it, to Garda's dismay. Eric Bartell, promoter, arrives to dupe Stevens. When Ed Connors, New York racketeer arrives, Bartell is mysteriously murdered. Joel and Garda set out to investigate the murder.
