Open House is a side case in The Sinking City. This case is given by an Innsmouther called Walter at the Fish Market.
A note could potentially lead Charles Reed to Walter. This note is found on a table in the Devil's Reef Hotel, entitled "To Walter".
He asks Charles to put incense burners in his properties to ward off wylebeasts infesting the places that he would like to rent, and to take photos as proof.
