chunk: As a gesture to Ripley, Dickie agrees to travel with him on a short holiday to Sanremo. Sensing that Dickie is about to cut him loose, Ripley finally decides to murder him and assume his identity. When the two set sail in a small rented boat, Ripley beats him to death with an oar, dumps his anchor-weighted body into the water, and scuttles the boat.
  Ripley assumes Dickie's identity, living off the latter's trust fund and carefully providing communications to Marge to assure her that Dickie has dumped her. Freddie Miles, an old friend of Dickie's from Dickie's same social set, encounters Ripley at what he supposes to be Dickie's apartment in Rome; he soon suspects something is wrong. When Miles finally confronts him, Ripley kills him with an ashtray. He later disposes of the body on the outskirts of Rome, attempting to make police believe that robbers have murdered Miles.
