At a Halloween photo walk, Tara Linskey's private image appears in public. The threat is theatrical, cruel, and impossible to ignore. It is signed The Judgement. By morning, Tara is dead. Detective Bria Friday has worked ugly cases before, but this one is built from the things people perform and the things they hide: sex, access, passwords, jealousy, friendship, grief, and the vicious confidence of anyone who thinks shame is a weapon. Tara's circle offers suspects, witnesses, and versions of the truth that do not agree with each other. Mason Maloney should be peripheral. He is not. Still carrying the aftershocks of Cassandra O'Neill's case, Mason becomes one more unstable piece of Bria's investigation: witness, complication, and reminder that the past never stays politely closed. As Cork moves from Halloween spectacle to forensic fact, Bria has to find the person behind The Judgement before another private life is turned into evidence.Judas and the Ghost is Book 2 in the Memento Mori trilogy: a police-led Cork psychological crime novel about sexual privacy, coercion, grief, evidence, and the ghosts made by public cruelty. Best read after The Boy with the Crow.
