An excerpt from the interview:
The novel takes its name from the ‘Fire Dragon,’ who may or may not be real. It might be a new rogue Spirit, or it might simply be a superstition, or it might be the delusion of a deranged firefighter, or it might be an outright fraud to disguise acts of arson. Shuibai discovers a lot of arson fires set to cover up murder, terrorize the populace, and to destroy munitions belonging to rival forces, etc. No spoilers, so I will simply say, it’s near the end of the novel before we really find out what’s going on and the question of the Fire Dragon is resolved.
