THE CHECQUY: A centuries-old covert organization that protects the nation from supernatural threat. THE GRAFTERS: A centuries-old supernatural threat. After centuries of rivalry and bloodshed, two secret and otherworldly organisations - The Checquy and The Grafters - are on the verge of joining forces, and only one person has the supernatural skills - and the bureaucratic finesse - to get the job done: Myfanwy Thomas. But as a wave of gruesome atrocities sweep London, ingrained paranoias flare, old hatreds ignite and negotiations grind to a halt. It is up to Myfanwy to find the culprits before they trigger a devastating, all-out, supernatural war between the reluctant allies.
