It’s 1929 and Borya Melnikov is a mixed-race patrolman in Harbin’s Special District police force. Paired with the legendary senior Inspector Chinn, they are investigating a grisly murder. The trail leads them through the city’s most upscale boulevards to its seediest boroughs and even to the frontiers of Manchuria. Danger abounds in the form of ethnic prejudices, local power struggles, and a growing Red terror campaign. And with a brewing border war with the Soviet Union fueling the instability of the region, will the pair survive long enough to solve the murder?
