A university professor sees a painting in a museum in which a person very similar to his father is drawn, and he feels deeply that the resemblance does not stop at the symmetry of the two faces alone. A frightening intuition awakens within him, and he tries to meet a relative of the descendants of the man in the painting. The novel's hero enters the maze of dream and wakefulness, and the maze of memory with its ramifications, evoking stories in which the real is mixed with the imaginary, and little by little we find that we are faced with several narratives, each one of which brings us into a new loss, until we ourselves become walking on the border between dream and wakefulness. In "The Dark Bank," José María Merino writes about the other or the companion, and about the past and memory, in a wonderful labyrinthine structure, within a vast time that lies on the margins of hours and pulses, and offers us pure pleasure that stimulates our imagination and senses.
