Ghostwalk

In 2002, a Cambridge historian is found dead, floating down the river Cam, a glass prism in her hand, after researching a book about a series of suspicious circumstances surrounding Newton's appointment as a Fellow of Trinity College, Cambridge, in 1667. That year, three Fellows died and a fourth was expelled, having gone mad–leaving vacancies for new appointments and paving the way for Newton’s extraordinary scientific discoveries. When Lydia Brooke, at the request of her ex-lover, the historian’s son, steps in to finish the book, strange shows of light begin to play on the walls, and papers disappear only to reappear elsewhere. And when events escalate to murder, the present becomes entangled with the seventeenth century, with Isaac Newton at the center of the mystery.
