The Big Poison

An elderly couple vanishes from their quiet Los Angeles neighborhood without a trace. Dirty dishes on the table, an empty garage, and a half-full bottle of cyanide in the basement point toward something far worse than a simple disappearance. As Sergeant Joe Friday and Ben Romero unravel the lies of a smooth-faced nephew with too many alibis, the truth leads to a cold-blooded plan, a forged trail of checks, and a final confession at the edge of a pier.
