    But whoever this nameless woman was, and whatever befell her, is knowledge lost to another time. . . . Boston, 1830: In order to pay for his education, Norris Marshall, a talented but penniless student at Boston Medical College, has joined the ranks of local “resurrectionists”–those who plunder graveyards and harvest the dead for sale on the black market. Yet even this ghoulish commerce pales beside the shocking murder of a nurse found mutilated on the university hospital grounds. And when a distinguished doctor meets the same grisly fate, Norris finds that trafficking in the illicit cadaver trade has made him a prime suspect.
