Death in the Hallows - Jamie Sedgwick - Bog

This time, it's personal:
When Hank finds an old friend murdered by the mythical Excalibur blade, he vows to find the killer and bring him to justice. Little does Hank know that while he's investigating the illegal black market of enchanted weapons, the undercity's most powerful citizens are looking to end Hank's investigation permanently.
Crooked cops, power mad elites, and goblin gangsters are just the beginning of Hank's troubles. He'll stop at nothing to expose the killer, unless the killer finds him first.
