It was almost dark when she stood at last on Mrs.Rooke's doorstep, asking herself what she should do if Mrs.Rooke was away from home.
Mrs.Rooke was out, as it happened, but the maid-servant, who knew Nelly, and, like all servants, had been captivated by her pleasant, friendly ways, invited her in to await the lady's return.

Mrs.Rooke was expected back to tea.

With a smile on her lips she held the drawing-room door open for Nelly to enter.
Nelly passed through.

There was a big French screen by the door.
