Someone is setting fires in the city of Edo, capital of Japan. The shogun sends samurai Judge Ooka and his newly adopted son Seikei to find the firestarter. The trail leads them to Yoshiwara, the “floating world” where beautiful geishas perform nightly for rich and powerful men. Seikei must discover secrets in this mysterious place that take him to the brink of a burning roof—and death.
