The Debt to Pleasure (1996) won the 1996Whitbread Book Award in the First Novel category and the 1997 Hawthornden Prize. It was described as a skilful and wickedly funny account of the life of a loquacious Englishman named Tarquin Winot, revealed through his thoughts on cuisine as he undertakes a mysterious journey around France. The revelations become more and more shocking as the truth about the narrator becomes apparent. He is a monster, and yet an appealing and erudite villain.
Mr Phillips (2000) describes one day in the life of Victor Phillips, a middle-aged accountant who has been made redundant, but has yet to tell his family.

The book deals with other male, middle-class concerns, including money, family and getting older.

The novel deals with themes of inter-generational guilt, international inequality, cross-Channel refugee migration, climate change, and slavery. The Wall was included on the Booker Prize longlist for 2019.
