How do you stop an assassination when you're working with the number one suspect?

When secret organizations are forced to merge after years of enmity and bloodshed, only one person has the fearsome powers - and the bureaucratic finesse - to get the job done. Facing her greatest challenge yet, Rook Myfanwy Thomas must broker a deal between two bitter adversaries:

The Checquy - the centuries-old covert British organization that protects society from supernatural threats

The Grafters - a centuries-old supernatural threat

But as bizarre attacks sweep London, threatening to sabotage negotiations, old hatreds flare. Surrounded by spies, Chequy agent Felicity Clements is forced to work with Grafter Odette Leliefield to track down the culprits . . . although they both view the other as suspect number one.

This brilliant follow up to the acclaimed The Rook is a must-read for fans of The Umbrella Academy.
