Two unlikely allies race through the cobbled streets of 1920s London in search of a killer targeting Chinese immigrants.

London, 1924. When shy academic Lao She meets larger-than-life Judge Dee Ren Jie, his quiet life abruptly turns from books and lectures to daring chases and narrow escapes. Dee has come to London to investigate the murder of a man he'd known during World War I when serving with the Chinese Labour Corps. No sooner has Dee interviewed the grieving widow than another dead body turns up. Then another. All stabbed to death with a butterfly sword. Will Dee and Lao be able to connect the threads of the murders--or are they next in line as victims?

Blending traditional gong'an crime fiction with the most iconic aspects of the Sherlock Holmes canon, Dee and Lao's first adventure is as thrilling and visual as an action film, as imaginative and transportive as a timeless classic.
