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. "Fans of Sherlock Holmes, devotees of intricate crime, and lovers of historical London will thrill over The Murder of Mr. Ma ... With a plot as clever as Chinese veteran of WWI turned independent investigator Dee, and pacing as light-footed as the martial artists engaged in the frequent fisticuffs, this case has it all—even romance and authentic food, if you can stomach such things. I'm only miffed because I don't know when the next in the series will land on my doorstep."—Lyndsay Faye, author of Dust and Shadow
