Can you trust yourself when you don't know who you are? Syme uses his new
acquaintance to go undercover in Europe's Central Anarchist Council and
infiltrate their deadly mission, even managing to have himself voted to the
position of 'Thursday'. In a park in London, secret policeman Gabriel Syme
strikes up a conversation with an anarchist. Sworn to do his duty, when Syme
discovers another undercover policeman on the Council, however, he starts to
question his role in their operations. And as a desperate chase across Europe
begins, his confusion grows, as well as his confidence in his ability to outwit
his enemies. But he has still to face the greatest terror that the Council has -
its leader: a man named Sunday, whose true nature is worse than Syme could ever
have imagined...
