Praise for The Aosawa Murders NYT: Chosen as one of Most Notable Books of 2020. Strange, engrossing, stubbornly non-linear... Guardian: One of the Best Mystery Novels of 2020. Tantalising as a scene glimpsed through a half-open door, this is an utterly immersive puzzler in which nothing is entirely cut and dried. WSJ: Part psychological thriller, part murder mystery--is audacious in conception and brilliant in execution. The Times: Rich and strange, utterly absorbing. Globe and Mail: Can this book open up the world of Japanese crime in the way that The Girl With the Dragon Tattoo opened up Scandi Noir? I hope so. KIRKUS starred review: This dark and dazzling novel defies easy categorization but consistently tantalizes and surprises.
