“You have promised to save me; you have sworn to assist me, and the sacrifice is imperative?” Statham had said. “It is her honour—or my death!”

Each time he entered the grim portals of the silent house in Park Lane those fateful words recurred to him. The house of mystery seemed dark and chilly, even on those sunny days of early September, and old Levi seemed more sphinx-like and solemn. A dozen times had he been on the point of referring again to the matter, but each time he had refrained, for the millionaire’s manner had now changed. He was less anxious, and far more bright and hopeful. The discovery of Duncan Macgregor seemed to have wrought a great change in him, for the old Scot frequently spent the evening there, being telegraphed for from Glasgow, ostensibly to discuss business matters.

On the day following Marion’s visit to Park Lane Charlie was in Paris, having been sent there overnight upon a pressing message to the branch house in the Avenue de l’Opéra, for Statham Brothers were as well-known for their stability in France as in England.

Just before twelve o’clock, as he was issuing from the fine offices of the firm into the street, he stumbled against a rather short but well-dressed girl of about twenty-four. He raised his hat, and in English asked her pardon, whereupon, with a light laugh, she replied in the same tongue.

“Oh, really no apology is needed, Mr Rolfe.”

He glanced at her inquiringly.

“I—I really haven’t the pleasure of your name,” he said, still upon the doorstep of the office. At all events, she was rather good-looking and well-bred, even if her stature was a trifle diminutive. Her gown was in excellent taste, too.

“My name really doesn’t matter,” she laughed. “I know you quite well. You are Mr Charles Rolfe, old Mr Statham’s secretary.”

Then, in an instant, the troth flashed across his mind. This girl must be one of old Sam’s friends—one of his secret agents controlled and paid from the office in Old Broad Street.

“You wish to speak to me—eh?” he asked, in a quick, businesslike way.
