Burn the House Down 5

Anzu Murata, assuming a false name, sneaks into the Mitarai household under the guise of a housekeeper in search of the truth behind the fire 13 years ago-a fire for which her mother was labeled the criminal behind its outbreak. Makiko, the second wife of her father, Dr. Mitarai, receives Anzu into the house, and Anzu continues scouring the Mitarai home for clues behind the scenes as she gains Makiko's trust. With the cooperation of Makiko's older son, Kiichi, she closes in on the shared past between her mother and Makiko. Operating independently, Anzu's younger sister, Yuzu, reunites with their estranged father and presses him for help in determining the truth...but Makiko appears at the cafe where they're meeting!
