Maxim is giving Mrs. de Winter a look, as if he's telling her goodbye.
Mrs. Danvers has no idea why Rebecca would need a doctor. Rebecca couldn't stand doctors. Plus, she would have told her if something was wrong.
Colonel Julyan is starting to piece things together. The note to Favell makes a little more sense now: Rebecca must have wanted to tell him about her visit to the doctor.
They know what they have to do: the colonel and Maxim decide to visit the doctor in person. Favell can join them as long as he's not drunk.
Mrs. de Winter can tell by Mrs. Danvers' face that she hadn't realized Favell was accusing Maxim of murder.
The men decide to go to find Baker the next day at 9:00AM, but Favell says he's afraid Maxim will leave town that night.
Maxim gives Colonel Julyan his word that he won't flee, and arranges for Mrs. Danvers to lock the door from the outside when he and Mrs. de Winter go to bed.
Favell reaches out to shake hands with Mrs. de Winter, but she refuses. He says he doesn't blame her. It can't be fun for her to have her husband exposed as a murderer; he hopes she marries better next time. Ouch.
Once everyone leaves, Mrs. de Winter says that she's going to London, too, and Maxim agrees. He wants them to be together for whatever precious time they have left.
Still, Maxim is sure he won't be arrested right away. He'll get a good lawyer.
After dinner, Beatrice calls and talks to Mrs. de Winter. She's angry that Rebecca's death was ruled a suicide. She thinks some maniac must have sabotaged Rebecca's boat. She actually has all sorts of suggestions for them. Poor lady doesn't have a clue what's going on.
Maxim tells Mrs. de Winter to do whatever she can to get Beatrice off the phone. After she hangs up, Mrs. de Winter realizes how lucky it was that Beatrice wasn't at Manderley for all of this.
The phone rings again, but nobody answers. It's 10:00PM, and Mrs. de Winter sits at Maxim's feet. Maxim hold his wife in his arms and they "kiss […], feverishly, desperately, like guilty lovers who have not kissed before" (25.107).
