Molly Pargeter is a forty-something wife, and mother of three girls, who leads a stable but dull life in 1980s West London. She feels overweight and there is no passion in her relationship with her husband Hugh, who is secretly seeing another woman. For most of her life she has found escape in detective novels and books on art, especially about the fifteenth-century Italian fresco painter Piero della Francesca.

In a newspaper advertisement, Molly sees that a villa in Tuscany is to let and, after travelling to Italy to view the villa, "La Felicita", in the fictional town of Mondano, she decides to rent it for her family's August holiday. The villa is conveniently located for visits to the artistic centres of Florence and Siena, and also to Urbino, a day's drive away across the "Mountains of the Moon", where what Kenneth Clark called the world's greatest small picture awaits Molly: Piero's "Flagellation".

Water problems emerge in the first week of the holiday: the swimming pool becomes empty and there is no running water in the villa. In the second week, when the body of the ex-pat letting agent is discovered, also in an empty swimming pool, Molly suspects foul play. She becomes more involved with the local town of Mondano and its inhabitants: an aristocrat, a wealthy socialite, and several ex-pats who all seem to be hiding something, and is intrigued about the identity of the villa's absent owner, whom she knows only as "S. Kettering".

The search for the reason behind the disappearing water and the corpse, and discovering who S. Kettering is, becomes an obsession which leads Molly across the "Mountains of the Moon" to encounter more than just the small painting.

The Piero della Francesca Trail is an excursion which traces the works created by Piero della Francesca in Arezzo, Monterchi, San Sepolcro (his birthplace) and Urbino. To his contemporaries, Piero was admired as a mathematician and geometer as well as a painter, and today his paintings are celebrated for their serene humanism and use of geometric forms.

Summer's Lease has made famous the Piero della Francesca Trail, which sees Molly set out from the Chianti District near Siena and travel to view the following paintings of Piero della Francesca:

1. The Legend of the True Cross, Basilica di San Francesco d'Assisi, Arezzo
2. The Pregnant Madonna, Museo della Madonna del Parto, Monterchi
3. The Resurrection, Museo Civico, San Sepolcro
4. The Flagellation, Galleria Nazionale delle Marche, Palazzo Ducale, Urbino

Molly and her elusive landlord Buck Kettering share a love of the art work of Piero della Francesca. The Piero della Francesca Trail ultimately leads Molly to Buck, who for reasons of his own does not want to be found.
