Read it through once

Six or seven days passed. Archer heard nothing from Madame Olenska, and became aware that her name would not be mentioned in his presence by any member of the family. He did not try to see her; to do so while she was at old Catherine's guarded bedside would have been almost impossible. In the uncertainty of the situation he let himself drift, conscious, somewhere below the surface of his thoughts, of a resolve which had come to him when he had leaned out from his library window into the icy night. The strength of that resolve made it easy to wait and make no sign.
