Former best friends who built their careers writing about a single work of art meet after a decades-long falling-out. One of them, called to the other’s deathbed for unknown reasons by a “relatively short” nine-page email, spends his flight to Berlin reflecting on Dutch Renaissance painter Count Hugo Beckenbauer and his masterpiece, Saint Sebastian’s Abyss, the work that established both men as important art critics and also destroyed their relationship. A darkly comic meditation on art, obsession, and the enigmatic power of friendship, Saint Sebastian’s Abyss stalks the museum halls of Europe, feverishly seeking salvation, annihilation, and the meaning of belief.
