Drained (Agent Hank Rawlings, #1)

A known serial killer is once again taking lives in Chicago. Bodies drained of blood are being strewn across the city. For former Tampa homicide sergeant, Hank Rawlings, tracking down the man responsible for the killings becomes his first assignment at his new position, agent in the FBI's homicide division of the serial crimes unit. Almost before the ink dries on the new job's acceptance papers, Hank finds himself in Chicago, knee-deep in an investigation with a mounting body count. While every lead brings him and his partner closer to the killer, the one that puts them directly in front of him threatens them most.
