Dalrymple seemed little moved by the solemn invocation. It meant little enough to him.

"I must tell you a short story," he replied quietly. "Unless I tell you, you cannot understand. I have set my life upon your love, and I have gone so far that I cannot save my life except by you—my life and my honour. Will you listen to me?"

She nodded, and he heard her draw a quick breath. Then he began his story, putting it together clearly, from the facts he knew, in very few words. He told her how Annetta must have mistaken the bottle on his table for camphor, and how he had found her dead. Nothing would save him from the accusation of having murdered the girl but the absolute disappearance of her body. Maria shuddered and turned her head quickly when he told her that the body was lying under the postern arch behind the garden wall. He told her, too, that the boy was by this time asleep beside the mule on the path beyond. Then he told her of his plan, which was short, desperate, and masterly.

"You must tell no one that the abbess is dead," he said. "Go out through your cell into the garden, as soon as I am gone, and when I tap at the postern open the door. Leave a lamp in your cell. I will do the rest."

"What will you do?" asked Maria, in a low and wondering tone.

"You must lock the door of your cell on the inside and leave the lamp there," said Dalrymple. "You will wait for me in the garden by the gate. I will carry the poor girl's body in and lay it in your bed. Then I will set fire to the bed itself. Of course there is an under-mattress of maize leaves—there always is. I will leave the lamp standing on the floor by the bedside. I will shut the door and come out to you, and I can manage to slip the bolt of the garden gate from the outside by propping up the spring from within. You shall see."

"It is horrible!" gasped Maria. "And I do not see—"

"It is simple, and nothing else can save my life. Your cell is of course a mere stone vault, and the fire cannot spread. The sisters are asleep, except the portress, who will be far away. Long before they break down your door, the body will be charred by the fire beyond all recognition. They will see the lamp standing close by, and will suppose that you lay down to rest, leaving the lamp close to you—too close; that the abbess died while you were asleep, and that you had caught fire before you waked; that you were burned to death, in fact. The body will be buried as yours, and you will be legally dead. Consequently there will not be the slightest suspicion upon your good name. As for me, it will be supposed that I have procured other clothes for Annetta, thrown hers into the laboratory and carried her off. In due time I will send her father a large sum of money without comment. If you refuse, I must either be arrested, convicted, and sentenced to death for the murder of a girl who killed herself without my knowledge, or, as is probable, I shall go out now, sit down in a quiet place, and be found dead in the morning. It is certain death to me in either case. It would be absolutely impossible for me to get rid of the dead body without arousing suspicion. If it is wrong to save oneself by burning a dead body, it is not a great wrong, and I take it upon myself. It is the only wrong in the matter, unless it is wrong to love you and to be willing to die for you. Do you understand me?"

Leaning back against the door of the parlour, Maria Addolorata had almost unconsciously lifted her veil and was gazing into his eyes. The plan was horrible, but she could not help admiring the man's strength and daring. In his voice, even when he told her that he loved her, there was that quiet courage which imposes itself upon men and women alike. The whole situation was as clear as day to her in a moment, for all his calculations were absolutely correct,—the fire-proof vault of the cell, the certainty that the body would be taken for hers, above all, the assurance of her own supposed death, with the utter freedom from suspicion which it would mean for her ever afterwards. Was she not to be buried with Christian burial, mourned as dead, and freed in one hour from all the consequences of her life? It was masterly, though there was a horror in it.

She loved him more than her own soul. It was the fear of bringing shame upon her father and mother that had held her, far more than any spiritual dread. It was not strange that she should waver again when he had unfolded his scheme.
