Makk had the misfortune to be born on a day believed to be so unlucky that his parents barely paused long enough to get him tattooed with the outcast mark before dumping him at an orphanage. The stigma of that mark is so strong that before becoming a cop Makk considered joining the House, planet Dib's religious organization, simply because some of the monks wear concealing robes that would hide it. The city of Velon's best detective also grew up in an orphanage and is therefore familiar with their compound when a scholarly monk is found murdered. Almost from the beginning this isn't a typical case. The monk, Orno, is the younger brother of Velon's most notorious criminal. Orno had recently stolen a priceless ancient religious text that no one can read, but it appears to discuss the Culling, when the god known as the Outcast will return and bring about the apocalypse. Then, just to really annoy Makk, he gets saddled with a shiny new detective as a partner. Everyone wants the case solved without any secrets being revealed, but in a world where independent reporters record everything with drones and conspiracy theories are more common than facts, Makk will have difficulty distinguishing the possible from the impossible.

The powers that be will cut any corner and take any risk they deem necessary to get ready, because if they fail there will be no humans left to condemn their actions as immoral.
