When she receives a wedding invitation from one of her former patients, forensic psychiatrist Dr Claire Roget is more than a little alarmed. Highly intelligent and manipulative, Jerome Barclay suffers from a severe personality disorder.

With no proof as to Jeromes possibly murderous intentions, Claires hands are tied. Can she prevent a tragedy unfolding? And is Claire herself at risk?
