"Veldaren aches for a purge, and I will be the one to deliver it. Cry out at me if you wish, but it will change nothing. The gold is spent, the orders are given. Let the blood flow." ---- It's been five years since Haern faked his death to escape the tyranny of his father. He has become the Watcher, a vicious killer who knows no limits, and whose hatred of the thief guilds is unrivaled. But when the son of Alyssa Gemcroft, one of the three leaders of the powerful Trifect, is believed murdered, the slaughter begins anew. Mercenaries flood the streets, with one goal in mind: find and kill the Watcher.
