Agent Magnus promotes Amari to Junior Agent and entrusts her with the briefcase and the Key Holder’s identity. The two of them visit Moreau in Blackstone Prison; on the way, Amari confesses to Agent Magnus that Maria is a magician and probably used tech magic to breach the Bureau’s security. As Moreau taunts them from his cell, Amari recalls Madame Violet’s words that she should not trust “that which giggles and grins” (341). Following a hunch, Amari casts a spell that dispels illusions, revealing that the “Moreau” in front of them is not the real Moreau: They never had him in the first place. The man they have imprisoned is merely an apprentice disguised as Moreau. Amari and Agent Magnus realize with horror that this means that Moreau has the Black Book now.

Amari and Agent Magnus are taken to Director Van Helsing’s office. Director Van Helsing demotes Amari, once again reaffirming his stance against magicians. He then accuses Agent Magnus of being a traitor and stealing the Black Book. Agent Magnus insists he’s being framed, but he surrenders for Amari’s sake.

Determined to make matters right, Amari takes it into her own hands to find the Key Holder and stop Moreau.
