On a chilly November morning, eighty-eight-year-old Iris Blum goes missing from Azalea Court, a six-bungalow development on the grounds of a long-closed state mental hospital. Her husband, Asher Blum, was the last head psychiatrist at the hospital and is writing a book about the treatment of mental illness. Their daughter Lexi, the neighbors, and police detective McPhee suspect Dr. Blum of being involved in Iris-s disappearance. When the searches and interviews come up empty, the neighbors dig into the past-Asher-s childhood experiences with anti-Nazi partisans in the forests of Poland, unethical practices at the mental hospital, and Iris-s mysterious best friend, Harriet. The neighbors of Azalea Court, Lexi, Harriet, and Detective McPhee narrate this story together, uncovering ghosts, secrets, and lies.
