A politically sensitive murder is detected amid the chaos of a deadly plague in this “stellar . . . well-crafted” mystery set in Restoration London (Publishers Weekly, starred review).

It’s 1665, and the Black Death has London in its hideous grip. It’s bad news for everyone . . . almost. For a mysterious killer, it presents an opportunity to hide a dead body among a city full of them. But as corpses are collected and brought to the burial pit, one of the bodies is revealed to have a knife in its back.

When the victim is identified as an agent of the King’s spy network, fixer John Grey is called in to handle the situation—and, above all, locate the sensitive documents the agent had been carrying at the time of his demise. Now Grey must navigate the deadly pestilence as he uncovers a potentially explosive conspiracy.
