On the last morning, the sun broke through the Cambridge rain. Chloe died at 7:43 a.m., with her hand in his. Alistair Norris returned to his college rooms. He sat at his desk. The silver die-shaped letter opener lay where he’d left it. He opened the drawer marked "Past States." Inside, beneath a folded program from a long-ago conference, was the postcard of the Maine lighthouse.
But on this particular Tuesday, a letter arrived. It was not an email or a text. It was a thick, cream-colored envelope, addressed in a looping, unsteady hand. He sliced it open with a letter opener shaped like a silver die (a gift from a long-ago PhD student).
“You came,” she said. Her voice was a dry rustle.
He began to write a different chapter instead. He called it The Weight of Yesterday: Why the Past Always Returns .
He taped it to the wall above his desk. Then he opened his laptop and deleted the final chapter of his new book—the one titled The Memoryless Self .
The past came flooding back, not as a sequence of independent steps, but as a single, unbearable weight. And he realized his great mistake: a Markov chain is a beautiful abstraction, but a human being is not. A human being carries every previous state, not in the mathematics, but in the marrow.
His daughter, Chloe, had stopped speaking to him three years after that. He received a postcard from her once—a photo of a lighthouse in Maine. He placed it on the mantel, but after a week, he filed it under "Past States" in a drawer and never looked again.
