The Newton Letter- Available March 2026

A unforgettably elegant tale of obsession and the fragile line between reason and desire.

In this compact literary gem, a historian retreats to a quiet cottage in rural Ireland to complete a biography of Isaac Newton—but the work stalls when he becomes absorbed by a mysterious letter Newton wrote in 1693, hinting at a personal and philosophical crisis. As the historian tries to understand the letter’s meaning, his own life begins to spiral.

Drawn into the lives of the people around him—Charlotte, cool and distant; Ottilie, impulsive and alluring; and Edward, eccentric and watchful—he starts to lose his grip on both his project and his perspective. Like Newton, he is undone not by science, but by the murky, unmeasurable forces of the human heart.

Banville’s prose is lyrical and precise, and The Newton Letter is both a meditation on genius and a portrait of quiet unraveling. A must-read for fans of psychological fiction and literary elegance.
