Theresa Bateman is a junior professor trying, and struggling, to establish herself in the art world. Then one day, she receives a mysterious tarot card in the mail from a stranger. A tarot card that may or may not belong to the most famous deck in the world-one only ever rumoured to exist: the lost tarot of Surrealist artist Lark Ringold, said to have been created shortly before his tragic death. Could this card really belong to Ringold's tarot? Why, if so, was it sent to Theresa? And who is the elderly woman who was holding onto it for all these years-and why? Theresa soon finds herself drawn into the mystery of the tarot card, and into the surrounding, deeply entwined mysteries of Nell, Lark and the Shown. The story she unspools is a web of passion, violence and deceit. And before long, her quest for the truth becomes a battle against the art establishment, against history, and against time-with the potential to change the art world, and herself.
