They arrive alive.
They always leave dead.

I am Jack Steen, the night nurse on the death ward of an Asylum for the Criminally Insane. Before my patients die, they give me their final confession-the truth they never told anyone else.
In Killer Grandparents, the confessions come from killers who lived long enough to be trusted. They raised families. They were loved. And they learned how to hide their crimes for decades.

These killers are expert manipulators. They could be lying to me.

Or maybe they're telling the truth.

Either way, now they're talking to you.
