北洋夜行记

In the summer of 2016, a seller of old books in Panjiayuan of Beijing died mysteriously, and on the crime scene, a journal in the Republic of China that had never been published was found, which recorded a series of criminal cases and the investigation of mysterious events during the reign of the Northern Warlords. Jin Zui, the friend of the deceased bookseller, was researcher of legends in the city. And he found that the journal contained some truth that was overlooked by history, and the unknown sides of many eminent figures, and it belonged to a secret group-the nightcrawler.
