About The Book

An Edgar Award Finalist for Best First Novel

For fans of Jacqueline Winspear and Charles Todd, Murder by Degrees is a “fresh…twisty” (Michelle Richmond, New York Times bestselling author) historical mystery set in 19th-century Philadelphia, following a pioneering woman doctor as she investigates the disappearance of a young patient who is presumed dead.


Philadelphia, 1875: It is the start of term at Woman’s Medical College of Pennsylvania. Dr. Lydia Weston, professor and anatomist, is immersed in teaching her students in the lecture hall and hospital. When the body of a patient, Anna Ward, is dredged out of the Schuylkill River, the young chambermaid’s death is deemed suicide. But Lydia is suspicious and she is soon brought into the police investigation.

Aided by a diary filled with cryptic passages of poetry, Lydia discovers more about the young woman she thought she knew. Through her skill at the autopsy table and her clinical acumen, Lydia draws nearer the truth. Soon a terrible secret, long hidden, will be revealed. But Lydia must act quickly before she becomes the next target of those who wished to silence Anna.

Reading Group Guide

The title Murder by Degrees is from an Emily Dickinson poem, quoted in the epigraph:

“The Whole of it came not at once--

'Twas Murder by degrees--

A Thrust—and then for Life a chance--

The Bliss to cauterize--

The Cat reprieves the Mouse

She eases from her teeth

Just long enough for Hope to tease--”
