What I'm Reading: The Talented Mr. Ripley by Patricia Highsmith

He couldn’t use the Rome American Express as Tom Ripley, but he had to keep Tom Ripley with him, his passport and his clothes in order for emergencies like Marge’s telephone call this morning. Marge had come damned close to being right in the room with him. As long as the innocence of Dickie Greenleaf was debatable in the opinion of the police, it was suicidal to think of leaving the country as Dickie, because if he had to switch back suddenly to Tom Ripley, Ripley’s passport would not show that he had left Italy. If he wanted to leave Italy—to take Dickie Greenleaf entirely away from the police—he would have to leave as Tom Ripley, and re-enter later as Tom Ripley and become Dickie again once the police investigations were over. That was a possibility.

It seemed simple and safe. All he had to do was weather the next few days.

"It seemed simple and safe"? Tom Ripley, your brain is a maze full of cats.
