Earthly Delights

In Earthly Delights, the story begins with the death of your favorite uncle, whom you've not seen for many years, and the unusual inheritance you receive from him — a portrait of a beautiful woman entitled Earthly Delight. Your uncle writes that pleasures and rewards will be yours if you keep the picture, and exhorts you not to sell it. When a stranger approaches you offering an enormous sum for the work, your suspicions are aroused and the adventure of Earthly Delights begins.
