Edinburgh, 1854, and a killer stalks the streets.

Body parts have been found across the city - a foot in the Surgeon's Hall, another beneath a debtor's floorboards, more pieces in the soil of a freshly filled grave - and Will Raven, assistant to the great Dr Simpson, is being asked questions about the crime.

His day job is demanding enough, striving to make his name as an obstetrician, and his home life with a second child on the way is exhausting. But Will usually finds the company of his colleague Sarah Fisher, a young widow and fellow-trainee, reviving. She is unrepentantly curious about all things: medicine, upcoming scientific advances like mesmerism, and details of this strange crime. So what is it about this killing that is beginning to turn Will into a man he doesn't recognise?

As the clues converge and all the evidence begins to point towards a dark connection between Will's past and Sarah's own investigations, both must use their full skills to prevent the most terrible crime of all . . .
