As the gilt clock on the mantel-piece hurriedly struck six, corroborated in the distance by the slow booming of Big Ben, a page boy knocked at Diana's sitting-room door, announcing two gentlemen waiting below, to see Miss Rivers.

"Show them up," commanded Diana; and, rising, stood on the hearthrug to receive them.

Mr. Inglestry entered, suave and fatherly, as usual; followed by a dark young man, who, hat in hand, looked with nervous admiration at the tall girl in green velvet, standing straight and slim, with her back to the fire.

She shook hands with Mr. Inglestry, who presented Mr. Ford, of the firm of Ford & Davis, of Riversmead.

"Well?" said Diana.

She did not sit down herself, nor did she offer a chair to Mr. Ford, of the firm of Ford & Davis, of Riversmead. A gleam of sudden anger had come into her eyes at sight of the young man. She evidently intended to arrive at once at the reason for this unexpected interview.

So Mr. Ford presented a sealed envelope to Diana.

"Under private instructions, Miss Rivers," he said, with a somewhat pompous air of importance; "under private instructions, from your uncle, the late Mr. Falcon Rivers, of Riverscourt, I am to deliver this envelope unopened into your hands, in the presence of Mr. Inglestry, on the eve of your marriage; or, should no marriage previously have taken place, on the eve of the anniversary of the death of your late uncle."

Diana took the envelope, and read the endorsement in her uncle's characteristic and unmistakable handwriting.

"So I see," she said. "And furthermore, if you carry out these instructions, and deliver this envelope at the right time, and in every respect in the manner arranged, payment of fifty guineas is to be made to you, out of the estate, for so doing. Also, I see I am instructed to open this envelope in the presence of Mr. Inglestry alone. Well, you have exactly carried out your instructions, Mr. Ford, and no doubt Mr. Inglestry will see that you receive your fee. Good-evening."
