The Locked Rooms of the Twin Snakes is the fourth book in the
Lychee Kamiki series starring the titular high school prostitute detective, and I think it’s the perfect entry to read in the Year of the Snake. The book explores the past of Hiroshige Aikawa, a recurring character from the previous books that’s a policeman and one of Lychee’s clients. Other than the hardcore sex scenes, this book provides basically exactly what I’m looking for, with a wild but well-clued solution and a streamlined investigation with basically no fat to cut.
