Castle and Becket bicker about compromise regarding a shared living space while investigating the murder of a famous author and the unofficial relationship therapist of the New York jet-set. It looks like VIP clients, such as the discreetly divorce-planning Warner couple, who hired an ex-con private detective, wanted to protect their secrets. But the team finds out she actually held her own secret and a giant flawless diamond, worth an insane fortune and even an armed attack in daylight on Ryan and Esposito.
