Ripley's Game
 

In Ripley’s Game (1974), the references are fairly sparse, the story concentrating on his friend (a Derwatt owner) Reeves’ problems with mafia infiltration of his business, the successful but unrewarding assassination of some mafia figures (partially by an acquaintance, Jonathan) and Ripley’s eventual escape from suspicion and blame. 

When Jonathan visited Reeves,

‘Jonathan had realised that the painting over the fireplace, a pinkish scene of a bed with an old person lying on it – male or female? – apparently dying, really was a Derwatt’ . [N1]

Towards the end, Jonathan is at Tom Ripley’s house

 ‘He glanced at the painting that Tom had said was called Man in Chair, by Derwatt, over the fireplace, maybe destroyed now’
