FOUR UNSOLVED MURDERS
In 1959, The Walker family murders shook Florida. At one time, 587 people were considered suspects - but 60 years later the investigation remains unsolved.
ONE FINAL CASE
Former FBI agent Brigid Quinn is trying to enjoy life after work. But when The Walker case comes up, she's only too happy to postpone retirement a little longer.

Quinn is reluctant to draw comparisons with another high-profile case of the time: the Clutter family murders, made infamous by Capote's IN COLD BLOOD. But the similarities are impossible to ignore, and perhaps Perry Smith and Dick Hickok, executed at the time, weren't acting alone - in both cases.
