In the depths of the ill-reputed Green Dolphin bar in Toronto, Tancred Palmieri, a talented thief with extravagant tastes, encounters Willow Azarian, an aging heroin addict. She reveals to Tancred that her very wealthy father has recently passed away, leaving each of his five children a mysterious object that provides a clue to the whereabouts of a large inheritance. Willow enlists Tancred to steal these objects from her siblings and solve the puzzle.
A Japanese screen, a painting that plays music, an aquavit bottle, a framed poem, and a model of Frank Lloyd Wright's Fallingwater … Are these really clues, or has Tancred fallen victim to the delusions of a junkie?
Inspired by a reading of Treasure Island, The Hidden Keys questions what it means to be honourable and faithful in the face of desire.
