What began as an ordinary case of dog killing caught Da Liu's attention when a gun was involved. Ballistics testing revealed that the weapon was connected to a police officer's murder ten years earlier. As Da Liu and his team searched for the gun, they cracked one major firearms case after another.
This realistic novel stays true to life. One gun leads to a string of gun-related crimes, and each case is solved in its own distinctive way. Both the police officers and the criminals have vivid, distinctive personalities, giving the characters depth and the story plenty of conflict.
Written in a "docudrama" style, the novel portrays the real working lives of grassroots police officers: their demanding workloads, their painstaking investigative methods, their advanced crime-solving techniques, their commitment to truth and accuracy, and their busy, on-the-go lives. This is a crime-solving novel brimming with the realities of everyday life.
