Double Down

A good-looking dame walks into a detective's office and asks him to solve her murder. Plenty of punchlines follow. Inga checks out of a sanitorium just in time to help. There's a doppelganger mystery, Rick must tail his ex and Inga's ex-employer — who happen to be getting married in Vegas, if they survive being shot down into the Grand Canyon. Rick and Inga dive into the murky underworld of L.A. and Vegas, just in time for an A-Bomb test.
