It is now June 11, and Marian expects Laura to return from her honeymoon on June 12. Count Fosco and Madame Fosco, Laura’s aunt, will also be staying at Blackwater over the summer. Marian arrived at Blackwater Park, Sir Percival’s house in Hampshire, the previous day; she finds the place oppressive and gloomy.

From letters and newspaper clippings, Marian knows that Walter has arrived in Honduras and departed with his group for an inland expedition. Meanwhile, Anne Catherick is still missing. Mr. Gilmore has fallen ill and has stopped working on his doctor’s orders, so the family now has a new lawyer. Mrs. Vesey is now living with her sister in London.

Marian has received letters from Laura throughout her honeymoon, but these are not forthcoming on the question that interests Marian most: whether her sister is happy. Laura is as reserved regarding Count Fosco as she is when talking about Sir Percival, though she approvingly remarks that her aunt, who was outspoken as a single woman, has become “quieter” in her married state. Marian senses that Laura dislikes Fosco.

On June 12, Marian explores Blackwater Park. One part of the house is very dusty and falling into disrepair, while the lake outside is murky, dark, and full of reptile and amphibian life.
