Ghostwalk by Rebecca Stott

When the brilliant historian Elizabeth Vogelsang is found drowned under mysterious circumstances, her unfinished manuscript on Isaac Newton’s alchemy draws her former student, Lydia Brooke, back to Cambridge. As Lydia completes the work, she becomes entangled in a series of strange events — echoes of the past seeping into the present. Secrets buried in the university’s ancient walls resurface, revealing a web of obsession, betrayal, and murder that spans centuries.

Atmospheric, erudite, and hauntingly original, Ghostwalk blurs the boundaries between science and mysticism, history and the supernatural — a mesmerizing literary mystery of intellect and ghosts.
