Green Arrow, Vol. 4: Fresh Water Kills

An ecological disaster has rocked Star City to its core and left Oliver Queen with more questions than answers. Who is the Fresh Water Killer, and why does he seem inextricably linked to Queen himself?

Star City is in the crosshairs of a madman calling himself the Fresh Water Killer, leaving Green Arrow scrambling for answers as he tries to save the city he protects. But the Fresh Water Killer is more than meets the eye and is harboring dark secrets of his own with connections to Ollie’s past.
