Renowned cookbook writer Paul Stuart, renewed and refreshed from his time in Tuscany, has returned to Scotland to work on his new book, The Philosophy of Food in Six Easy Chapters. Writing, though, is complicated by Paul's changed domestic circumstances. His editor and new girlfriend, Gloria, has moved in with him despite not being specifically invited, and she's brought her two rather demanding Siamese cats. When Paul's cousin, Chloe, suggests Paul visit her in the French countryside, Paul jumps at the chance. However, once he arrives, he finds his fortunes tangled up with the infamous local restaurant that gives the book its title.
