the valet would be busy in one of the other rooms, that she might have that one quick peep in secret, and unmolested.

Gently, on tip-toe, she crossed the landing and, like Blue Beard’s wife, trembling half with excitement and wonder, she paused a moment on the threshold, strangely perturbed and irresolute.

The door was ajar, and she could not see anything within. She pushed it open tentatively: there was no sound: Frank was evidently not there, and she walked boldly in.

At once she was struck by the severe simplicity of everything around her: the dark and heavy hangings, the massive oak furniture, the one or two maps on the wall, in no way recalled to her mind the lazy man about town, the lover of race-courses, the dandified leader of fashion, that was the outward representation of Sir Percy Blakeney.

There was no sign here, at any rate, of hurried departure. Everything was in its place, not a scrap of paper littered the floor, not a cupboard or drawer was left open. The curtains were drawn aside, and through the open window the fresh morning air was streaming in.

Facing the window, and well into the centre of the room, stood a ponderous business-like desk, which looked as if it had seen much service. On the wall to the left of the desk, reaching almost from floor to ceiling, was a large full-length portrait of a woman, magnificently framed, exquisitely painted, and signed with the name of Boucher. It was Percy’s mother.

Marguerite knew very little about her, except that she had died abroad, ailing in body as well as in mind, when Percy was still a lad. She must have been a very beautiful woman once, when Boucher painted her, and as Marguerite looked at the portrait, she could not but be struck by the extraordinary resemblance which must have existed between mother and son. There was the same low, square forehead, crowned with thick, fair hair, smooth and heavy; the same deep-set, somewhat lazy blue eyes beneath firmly marked, straight brows; and in those eyes there was the same intensity behind that apparent laziness, the same latent passion which used to light up Percy’s face in the olden days before his marriage, and which Marguerite had again noted, last night at dawn, when she had come quite close to him, and had allowed a note of tenderness to creep into her voice.

Marguerite studied the portrait, for it interested her: after that she turned and looked again at the ponderous desk. It was covered with a mass of papers, all neatly tied and docketed, which looked like accounts and receipts arrayed with perfect method. It had never before struck Marguerite—nor had she, alas! found it worth while to inquire—as to how Sir Percy, whom all the world had credited with a total lack of brains, administered the vast fortune which his father had left him.

Since she had entered this neat, orderly room, she had been taken so much by surprise, that this obvious proof of her husband’s strong business capacities did not cause her more than a passing thought of wonder. But it also strengthened her in the now certain knowledge that, with his worldly inanities, his foppish ways, and foolish talk, he was not only wearing a mask, but was playing a deliberate and studied part.

Marguerite wondered again. Why should he take all this trouble? Why should he—who was obviously a serious, earnest man—wish to appear before his fellow-men as an empty-headed nincompoop?

He may have wished to hide his love for a wife who held him in contempt…but surely such an object could have been gained at less sacrifice, and with far less trouble than constant incessant acting of an unnatural part.

She looked round her quite aimlessly now: she was horribly puzzled, and a nameless dread, before all this strange, unaccountable mystery, had begun to seize upon her. She felt cold and uncomfortable suddenly in this severe and dark room. There were no pictures on the wall, save the fine Boucher portrait,
