One Thursday afternoon in the seniors' center, a decade-old cold case --their favorite kind-- leads the Thursday Murder Club to a local news legend and a murder with no body and no answers. A new foe they call Viking , wants Elizabeth to kill former KGB chief Viktor, or he will kill her sweet best friend Joyce. Activist marked for death Ron and psychiatrist Ibrahim chase clues for Viking's identity, and investigate mob-queen prisoner from last book. This third adventure ranges from a prison cell with espresso machine to a luxury penthouse with swimming pool high in the sky.
