Green Arrow. The Longbow Hunters. Book 1 TPB

On his forty-third birthday, Ollie Queen relocates from Star City to Seattle, Washington, the home of his girlfriend Dinah Lance. He changes his costume and abandons the use of his trademark trick arrows for more traditional archery equipment. As Green Arrow tries to track down a serial killer, the Seattle Slasher, killing prostitutes in the area, Black Canary attempts to infiltrate a drug racket which may have ties to Kyle Magnor, a wealthy shipping magnate.
