Wooser saves a turtle at the beach, and that turtle leads him to an underwater world... the next day he is found drowned.  The mysteries deepen as the case twists and turns.  A trick with the time tables, and the shadow of the true culprit lurking in the background...  Who is "The Animal Which must not be named?"  A shocking truth is about to be revealed... or if it is, that would be really cool, anyway.

dit été, et inversement !
I costumi da bagno 
 sono sono l'estate,
Roupas de banho significam verão,
