In an apricot-colored building in Zurich, surrounded by curiously planted forget-me-nots, Gaustine has opened the first “clinic for the past,” an institution that offers an inspired treatment for Alzheimer’s sufferers: each floor reproduces a past decade in minute detail, allowing patients to transport themselves back in time to unlock what is left of their fading memories. Serving as Gaustine’s assistant, the narrator is tasked with collecting the flotsam and jetsam of the past, from 1960s furniture and 1940s shirt buttons to nostalgic scents and even wisps of afternoon light. But as the charade becomes more convincing, an increasing number of healthy people seek out the clinic to escape from the dead-end of their daily lives—a development that results in an unexpected conundrum when the past begins to invade the present. Through sharply satirical, labyrinth-like vignettes reminiscent of Italo Calvino and Franz Kafka, the narrator recounts in breathtaking prose just how he became entrenched in a plot to stop time itself.
