The Mad Wanderer

In May, rain drizzles endlessly over Z City. On a solemn morning, the municipal public security bureau receives calls reporting four separate incidents at the same time:

A deaf-mute girl from a remote village, a glamorous online influencer, a supermarket cashier, and an airline pilot.

Four people of vastly different backgrounds and social standing, all mysteriously dead at the same time.

Strangest of all, during the autopsies, the lividity on their bodies blooms into brilliant mandala flowers...

A killer who paints with livor mortis has declared war on the city's police!!

Two Boeing planes take off an hour apart, yet someone can kill from a distance?

The world needs a quick-witted, upright police officer,

and at the same time,

it needs a madman...
