"Is that any distance from the house, Lady Billington-Smith?"
She looked at him, a worried frown in her eyes. "No. It's at the side of the house, about two minutes' walk from the garden-hall."
"How long did it take you to deliver Sir Arthur's message to Lester?"
"Well, I don't — A minute, I suppose."
"Did you say anything else to him?"
"I told him that Sir Arthur wanted him to mow the front lawn."
"Nothing else?"
"No. No, I'm sure that was all."
"And when you had delivered both these message. what did you do next?"
"I went through the kitchen-garden to the back of the house. Mrs. Twining and my sister were crossing the lawn, and they called to me."
