To keep up appearances, Audrey pretends to go on holiday to Spain, but she's actually hiding at the lodge with only Ned aware of her secret. She becomes suspicious when she sees Richard and Marjory skulking around the grounds together--but they're not romantically involved, they're only bird-watching. When Audrey 'returns' from her holiday, Richard tells her he knows her secret but agrees to keep quiet if she stops telling people he made his fortune through dodgy business deals.
