The second novel of the Goblin Slayer series.
No one can say that Goblin Slayer isn't good at his job – and that's why the unusual young adventurer and his party find themselves headed to the Water City on a very special quest. Sword Maiden, one of the greatest heroes the world has ever known, has personally requested that Goblin Slayer investigate a series of abductions and killings by goblins beneath the seemingly peaceful city. He and the rest of the group are up for the task, but why are goblins lurking in sewers that don't even have giant rats? Could there be more going on than Sword Maiden is saying?
