"Very good, sir!"

The servant was about to retire when the burly form of a uniformed warder blocked the doorway. He saluted.

"I understand Sir Reginald is away; can I speak to you a moment, sir?"

Jim glanced over his shoulder at Marjorie. She was hidden from sight, seated in a large armchair.

"Certainly," he replied. He crossed the room and stepped into the hall, closing the drawing-room door behind him.

As he did so a noise from the conservatory on the left of the fireplace startled Marjorie. The sound of a sudden crash. She listened a moment, then rose to her feet.

Very quietly stepping towards the door which led into the hot-house, she pulled back the curtain and peered through the glass panel.
