Pendergast is abruptly forced to accept an unthinkable condition of continued employment: the famously rogue agent must now work with a partner. Pendergast and his new teammate, junior agent Coldmoon, are assigned to Miami Beach, where a rash of killings by a bloodthirsty psychopath are distinguished by a confounding M.O.: cutting out the hearts of his victims and leaving them - along with cryptic handwritten letters - at local gravestones, unconnected save in one bizarre way.

FBI Agent Pendergast has taken Constance on a whirlwind Grand Tour. They head to Tibet, where Pendergast intensively trained in martial arts and spiritual studies.
