What is the main conflict in Up at the Villa by W. Somerset Maugham?

Mary Panton is recovering from the ordeals of losing her husband and dealing with attorneys in the mess that's left of their financial situation, when she has the opportunity to spend some time as a guest at a Tuscan villa owned by the Leonards. She finds herself spending a great deal of time seeing the sights, but then stops the running around and spends time at the villa, on the porch or in the garden, and it's there that her soul begins the process of recovery.
