When Colonel Roger Forsythe is murdered by an "exploding" birthday cake at the hotel Towarna Conrad on the island of Towarna everyone on the island becomes a suspect, but none of them did it.



Note: The Chief (Edward Platt) does not appear in this episode.




  • Despite repeated references to an "exploding" birthday cake, the cake does not actually explode. Instead, it has a model cannon mounted on it which fires at the victim when he blows out the candles.

Reality CheckEdit

  • The title refers to the term "whodunit", a sub-genre of detective fiction.
