Gustav Klimt's Portrait of a Lady, painted in Vienna in 1910, was bought by an anonymous collector in 1916, reworked by the artist one year later, and stolen in 1997, before reappearing in 2019 in the gardens of the Ricci-Oddi Museum in Italy. A shoeshiner on Wall Street, a young feather worker in Leobendorf, a prostitute in Houston, a poetry-loving Austrian, an elderly New York billionaire—spanning the 20th century, all these characters’ lives intertwine in the story of the painting, resonating with one another in this masterful saga of family secrets, dazzling success, thwarted love, disappearances, and tragedy.
