Ripley gets found out after the events in Talented mr Ripley by Minghella as he is in Plein Soleil by Clement

Ripley at the end of Talented movie kills  Peter. They are in a ship in a cabin registered to both. How Ripley justifies Peter's demise? Simulating suicide? This will draw attention to him and Meredith who knows him as Dickie learns that he  calls himself Tom Ripley.  Or he plunges Peter's body overboard  by night? Assuming he's not seen, how can he not denounce Peter' disappeaeance to the  Captain?  Again, that will draw attention to him. And someone in Greece will be waiting for Peter. Not only that, but Meredith could write Margie saying he met Dickie on the ship, or worse that the person she knows as  DIckie  is called Tom Ripley!  Marge and Dickie's father think him dead and Marge at the end of the movie Talented is convinced of Tom's guilt. Soon an investigation would be made, photos of Ripley divulgated and  compared with photos of Dickie.  Those will be shown to the Italian lady who rented "Dickie"the Roman apartment and maybe to the concierge of a certain San Remo hotel. Then an extensive thorough research of the sea near San Remo will reveal Dickie's body.  And Tom would  be in big trouble.. In the novel  there's no Meredith and Peter has only a very minor part and he is NOT  killed   And in the novel Marge does not even suspect Tom, as she does in Talented movie.  In Plein Soleil  Tom got found out and so will happen implicitly in Talented movie. A strange coincidence: the actor playing Freddy  in Plein Soleil vaguely resembles the actor playing Freddy in Talented
