That fancy of hers was not to be dismissed at will. Her mind was perversely busy now with an imaginative picture of the beauty of Mablethorpe House and the comfort and elegance of the life that was led there. Once more she thought of the chance which Miss Roseberry had lost. Unhappy creature! what a home would have been open to her if the shell had only fallen on the side of the window, instead of on the side of the yard!

Mercy pushed the letter away from her, and walked impatiently to and fro in the room.

The perversity in her thoughts was not to be mastered in that way. Her mind only abandoned one useless train of reflection to occupy itself with another. She was now looking by anticipation at her own future. What were her prospects (if she lived through it) when the war was over? The experience of the past delineated with pitiless fidelity the dreary scene. Go where she might, do what she might, it would always end in the same way. Curiosity and admiration excited by her beauty; inquiries made about her; the story of the past discovered; Society charitably sorry for her; Society generously subscribing for her; and still, through all the years of her life, the same result in the end--the shadow of the old disgrace surrounding her as with a pestilence, isolating her among other women, branding her, even when she had earned her pardon in the sight of God, with the mark of an indelible disgrace in the sight of man: there was the prospect! And she was only five-and-twenty last birthday; she was in the prime of her health and her strength; she might live, in the course of nature, fifty years more!

She stopped again at the bedside; she looked again at the face of the corpse.

To what end had the shell struck the woman who had some hope in her life, and spared the woman who had none? The words she had herself spoken to Grace Roseberry came back to her as she thought of it. "If I only had your chance! If I only had your reputation and your prospects!" And there was the chance wasted! there were the enviable prospects thrown away! It was almost maddening to contemplate that result, feeling her own position as she felt it. In the bitter mockery of despair she bent over the lifeless figure, and spoke to it as if it had ears to hear her. "Oh!" she said, longingly, "if you could be Mercy Merrick, and if I could be Grace Roseberry, now!"

The instant the words passed her lips she started into an erect position. She stood by the bed with her eyes staring wildly into empty space; with her brain in a flame; with her heart beating as if it would stifle her. "If you could be Mercy Merrick, and if I could be Grace Roseberry, now!" In one breathless moment the thought assumed a new development in her mind. In one breathless moment the conviction struck her like an electric shock. She might be Grace Roseberry if she dared! There was absolutely nothing to stop her from presenting herself to Lady Janet Roy under Grace's name and in Grace's place!

What were the risks? Where was the weak point in the scheme?

Grace had said it herself in so many words--she and Lady Janet had never seen each other. Her friends were in Canada; her relations in England were dead. Mercy knew the place in which she had lived--the place called Port Logan--as well as she had known it herself. Mercy had only to read the manuscript journal to be able to answer any questions relating to the visit to Rome and to Colonel Roseberry's death. She had no accompl ished lady to personate: Grace had spoken herself--her father's letter spoke also in the plainest terms--of her neglected education. Everything, literally everything, was in the lost woman's favor. The people with whom she had been connected in the ambulance had gone, to return no more. Her own clothes were on Miss Roseberry at that moment--marked with her own name. Miss Roseberry's clothes, marked with her name, were drying, at Mercy's disposal, in the next room. The way of escape from the unendurable humiliation of her present life lay open before her at last. What a prospect it was! A new identity, which she might own anywhere! a new name, which was beyond reproach! a new past life, into which all the world might search, and be welcome! Her color rose, her eyes sparkled; she had never been so irresistibly beautiful as she looked at the moment when the new future disclosed itself, radiant with new hope.

She waited a minute, until she could look at her own daring project from another point of view. Where was the harm of it? what did her conscience say?

As to Grace, in the first place. What injury was she doing to a woman who was dead? The question answered itself. No injury to the woman. No injury to her relations.
