Forensic detectives find traces of blood in the basement, and then the entire corpse, dismembered, the parts hidden behind a false wall and packed in boxes, each of the parts wrapped and doused in gasoline. The victim's identity is discovered through prints to be a prostitute named Maggie Karer. The dismemberment, "defensive mutilation," is so calculated and deliberate, the detectives wonder, are there more victims?

But Pirrera's first wife was named Beverly, and a woman named Lesa Davidson shows up at the police station to say she hasn't heard from her daughter-Beverly-in eight years. And Sam's estranged wife, Danielle, who is in fact alive, tells police that Sam had once told her he had killed his first wife and dumped her parts in a vat of molten steel at a steel plant. Detectives now pursue a double murder case, led by veteran homicide detective Peter Abi-Rashed, who had once chased a young Sam Pirrera on the streets of Hamilton's east end many years before.

The outcome is shocking - and a mystery remains.
