Mary did not ask where the library was, because she was suddenly inspired by a new idea. She made up her mind to go and find it herself. She was not troubled about Mrs. Medlock. Mrs. Medlock seemed always to be in her comfortable housekeeper’s sitting-room downstairs. In this queer place one scarcely ever saw anyone at all. In fact, there was no one to see but the servants, and when their master was away they lived a luxurious life below stairs, where there was a huge kitchen hung about with shining brass and pewter, and a large servants’ hall where there were four or five abundant meals eaten every day, and where a great deal of lively romping went on when Mrs. Medlock was out of the way.
