Pathfinder Roleplaying Game Superscriber
Not sure which book, perhaps the Game Mastery Guide, but you have very complete information:
- on the PRD: http://paizo.com/pathfinderRPG/prd/gameMasteryGuide/haunts.html#haunts
- on d20pfsrd: https://www.d20pfsrd.com/gamemastering/haunts/
The second link will take you to dozens of example haunts. The second book of the Rise of the Runelords campaign has a great set of haunts in n haunted house, you really can't go wrong modelling your plans on that shuddersome example.
