Mr and Mrs Robert Drummond lived in a pretty house in the Kensington district; a house, the very external aspect of which informed the passer-by who they were, or at least what the husband was. The house was embowered in its little garden; and in spring, with its lilacs and laburnums, looked like a great bouquet of bloom-as such houses often do. But built out from the house, and occupying a large slice of the garden at the side, was a long room, lighted with sky windows, and not by any means charming to look at outside, though the creepers, which had not long been planted, were beginning to climb upon the walls.
