"None whatever, mademoiselle. I watched her, and saw she carried the letter to the bank. As soon as the money was changed I left Croydon by air for Paris, and came on from Paris to Marseilles by aeroplane."

"You did well, François," she said, and patted his hand.

He would have seized hers, but she drew back.

"You have promised, François," she said with dignity, "and a French gentleman keeps his word."

François bowed.

He was not a French gentleman, but he was anxious that this girl should think he was, and to that end had told her stories of his birth which had apparently impressed her.

"Now will you do something more for me?"

"I will do anything in the world, Jean," he cried passionately, and again a restraining hand fell on his shoulder.
