Il mistero delle lettere perdute - Il regalo di mia madre

Actress Colleen Camp who previously portrayed Rita's Mother doesn't appear in this movie. The character is apparently killed in an unseen spelunking accident. Camp was apparently difficult to work with and was written out of all future SSD movies at the main casts request.

Just before Rita and Norman's wedding Gertrude tells a few of the other guests about Gabe, who is playing the guitar up front. She says he wrote a letter to the only woman he ever loved but the letter got lost in the mail and then she got lost in a hurricane but the POstables found her and reunited them. There are several things wrong with her re-telling. First of all Hattie wasn't the only woman Gabe loved, his first wife and baby daughter died in a fire. And it was after they got separated by the hurricane that Gabe wrote the letter to Hattie that ended up at the DLO which led the POstables to reunite Gabe and Hattie.
