How to Get a Love Novel for Herbert in Graveyard Keeper 2

To get a Love Novel for the town's guard captain in Graveyard Keeper 2, you'll need to complete a side quest involving the local looter gang and a man named Davy, whom you'll find inside the Dockside Club in the Port Area. Speak with Davy, and he'll ask you to clear out some zombies in the sewers. Form a squad of zombies, gear them up with the best equipment you can make, and head down into the sewers as per Davy's bidding. Once you're done exterminating the undead, you'll get a bunch of keys that you can give to Davy, and in return, he'll give you the Love Novel you need to progress Herbert's quest in Graveyard Keeper 2.
