Based on an actual murder case.

This was a very puzzling case. We had lots of blood, but no fingerprints. None of the neighbors had seen anything. Hank Triffitti had no enemies. He seemed to have a wife who genuinely loved him.

All we knew from the autopsy report was that the victim was struck from above with a sharp, bladed weapon. The perpetrator was right-handed, probably considerably taller than the 5 ft 10 victim. It appeared to be a single stroke, one massive stroke with a sharp weapon. The blow had been strong enough to cut through the victim’s left forearm (raised in defense) and the victim’s neck. One mighty blow.
