"The scene is the Yoshiwara pleasure quarter, where prostitution is legal and all kinds of entertainment are available for a price. Handsome young Lord Mitsuyoshi, heir to the shogun, lies stabbed to death in the bed of Lady Wisteria, one of Yoshiwara's most beautiful, popular courtesans. Lady Wisteria is the only apparent witness to the crime, but she has mysteriously disappeared. Detective Sano Ichiro, his wife Lady Reiko, and his chief retainer Hirata must solve the murder case before their enemies can destroy them."
