The assassination of a Treadstone agent leads two Blackbriar operatives down a rabbit hole of deceit and betrayal in this explosive new series from the world of Robert Ludlum's Jason Bourne.

A car explodes on a quiet Prague side street – and among the dead is an undercover Treadstone agent. It's not unusual for such men to meet their fates on an operation, but in this case there's one catch: none of the agent's superiors knows why he was there.

Two Blackbriar operatives, Helen Jouvert and Donovan Wade, are sent to investigate. Their search for answers will take them deeper into the world of conspiracy and fake news than they ever expected. Treadstone and Blackbriar, intelligence and counter-intelligence, may be two sides of the same coin, but they have one thing in common: answers can be the deadliest commodity of all.
