Sir Humphrey started. “Sir?”

“I am he,” said Robin quietly.

For a moment Sir Humphrey could find no words. This slim boy — that magic swordsman Letty raved about! No highwayman, no outlaw, as he had feared, but a Viscount’s son and heir! “You?” he gasped. “You are the man who saved my daughter? Barham’s son! You will excuse me, sir; I am completely taken aback! Are you indeed my daughter’s mysterious champion?”

“A grander term than I should have chosen, sir. I am the Unknown who killed Markham, certainly. But I beg you won’t mention it.”

“You are he! Sir, you must let me take your hand! I owe you more than I can ever hope to repay. Indeed, I scarcely know how to thank you, for words seem to be inadequate!”

Robin broke in, flushing. “Sir Humphrey, you will agree that gratitude is out of place when I tell you that I love your daughter. I am here today to ask you for your permission to pay my addresses to her in form.”

Sir Humphrey wrung his hand anew. His feelings were almost too much for him. At one moment he was under the gloomy conviction that the late appalling scandal had ruined his Letitia for ever; at the next a brilliant match for her was proposed to him. Her position in the world would be honourable beyond his wildest hopes, and no one would dare to talk scandal of the prospective Viscountess of Barham. He gave Robin to understand that he had a father’s blessing and suggested that he should send Letty to him at once.

Robin begged him, with a dancing smile, to lose no time in so doing. Sir Humphrey went off with quite a jaunty step.

In a few moments the door opened again to admit Letty. She was dressed all in primrose taffeta, with a riband through her curls. Her father had not told her who waited to see her; there was a wondering expression in the brown eyes, and she looked doubtfully at Robin.

He stood in the middle of the room, watching her, and said no word. The puzzled gaze ran over him slowly; a little hand stole to Letty’s breast and her eyes widened. The slight, strong figure was surely familiar. She saw him put a hand to his pocket, and bring out a string of pearls. On his little finger was a gold ring cunningly wrought.
