A Bala Desaparecida (2012)

Both movies were directed by Law Chi Leung, and Lau Chi Wan takes on his role as Dong Lu again. I honestly prefer The Bullet Vanishes over The Vanished Murderer, but both are really great.

Both films incorporate their own unique variations of the classic Holmes-and-Watson dynamic, with two seemingly incompatible but nevertheless well-matched characters that team up to solve a murder case. Highly recommended if you're a fan of period pieces that feature capable characters and unlikely partnerships, along with a dash of action, mystery, and bromance.
