In 1843, Edgar Allen Poe wrote the Tell-Tale Heart. It was a short story about a man who had killed and dismembered his victim, hiding him underneath the floorboards of his home. Throughout the work, the murderer was driven to insanity by the sound of a beating heart from underneath his feet.
More than 170 years later, the Kansas City Chiefs have become the living embodiment of that literature. This was a team dead and buried, left for dead and all but forgotten about by those on the outside. It was a finished work, with only the epilogue to write.
