Passage: Angel, totally disheartened, is leaving Sandbourne; Tess hurries after him and tells him that she has killed Alec, saying that she hopes she has won his forgiveness by murdering the man who ruined both their lives. Angel does not believe her at first, but grants her his forgiveness and tells her that he loves her. Rather than heading for the coast, they walk inland, vaguely planning to hide somewhere until the search for Tess is ended and they can escape abroad from a port. They find an empty mansion and stay there for five days in blissful happiness, until their presence is discovered one day by the cleaning woman.

Question: What was empty among arrival?
mansion
