how does one beat the haunted house mission and the millwater mission
at mill water talk to everyone in the main floor, then go up the stairs and into the first door on the bottom. You will find a potion in that room. after picking it up talk to the Winona(the second sons friend who works with potions), Lady Redwood(the murdered man's wife), and Irilina( the succubus) in that order once you do that you can solve the murder pretty easily.
