Shadowdance, book 3: A Dance of DeathDavid Dalglish2011

'We are the ones who own the night. We are the ones with blood on our hands. We are the reapers, the demons, the dark shadows wielding steel. We will not be denied our vengeance.' ---- Haern is the King's Watcher, protector against thieves and nobles who might fill the night with blood. Yet hundreds of miles away, an assassin known as the Wraith has begun slaughtering those in power, and leaving the symbol of the Watcher in mockery. When Haern travels south to confront his copycat killer, he finds a city ruled by the corrupt, the greedy, and the dangerous. Rioters fill the streets, and the threat of war with the mysterious elves hangs over all. To stop it, Haern must confront the deadly Wraith, and the man he might become.
