Warnecke died in 2010, and the story finally moved into the light.

He described a woman unsure of whether she wanted to be alone or in an affair.

Ultimately, a phone call Warnecke made to her to disclose his million-dollar debt would end their short-lived relationship.

Jackie held Warnecke to the same secrecy he would later ask of the biographer, and the ritual began.

My presence that evening was part of a ritual.

There were also photographs of Jackie and JFK on his Inauguration Day, which she asked Warnecke to keep.

Jackie read each letter in the pile before placing it into the fireplace.

Once each piece of paper was burned, the ritual was over, and Warnecke left.

One month later, Warnecke recalled speaking to Jackie for the last time over the phone.
