A sudden idea occurred to me, and I acted instantly upon its impulse. There was a second entrance through the morning room; and I dashed round to the other door, which fortunately yielded.
The sight that met my gaze was absolutely staggering. I stood upon the threshold aghast. Sir Bernard, his dark eyes starting from his ashen face, stood, holding a woman within his grasp, pinning her to the wall, and struggling to cover her mouth with his hands and prevent her cries from being overheard.
The woman was none other than Ethelwynn.
At my unexpected entry he released his hold, shrinking back with a wild, fierce look in his face, such as I had never before seen.
“Ralph!” cried my love, rushing forward and clinging to my neck. “Ralph! For God’s sake save me from that fiend! Save me!”
I put my arm around her to protect her, at the same instant shouting to Jevons, who entered, as much astounded as myself. My love had evidently come to town and kept an appointment with the old man. The situation was startling, and required explanation.
“Tell me, Ethelwynn,” I said, in a hard, stern voice. “What does all this mean?”
She drew herself up and tried to face me firmly, but was unable. I had burst in upon her unexpectedly, and she seemed to fear how much of the conversation I had overheard.
Noticing her silence, my friend Jevons addressed her, saying:
“Miss Mivart, you are aware of all the circumstances of the tragedy at Kew. Please explain them. Only by frank admission can you clear yourself, remember. To prevaricate further is quite useless.”
She glanced at the cringing old fellow standing on the further side of the room—the man who had raised his hand against her. Then, with a sudden resolution, she spoke, saying:
“It is true that I am aware of many facts which have been until to-day kept secret. But now that I know the horrible truth they shall remain mysteries no longer. I have been the victim of a long and dastardly persecution, but I now hope to clear my honour before you, Ralph, and before my Creator.” Then she paused, and, taking breath and drawing herself up straight with an air of determined resolution, went on:
“First, let us go back to the days soon after Mary’s marriage. I think it was about a year after the wedding when I suddenly noticed a change in her. Her intellect seemed somehow weakened. Hitherto she had possessed a strong, well-defined character; this suddenly developed into a weak, almost childish balance of the brain. Instead of possessing a will of her own, she was no longer the mistress of her actions, but as easily led as an infant. Only to myself and to my mother was this change apparent. To all her friends and acquaintances she was just the same. About that time she consulted this man here—Sir Bernard Eyton, her husband’s friend—regarding some other ailment, and he no doubt at once detected that her intellect had given way. Although devoted to her husband, nevertheless the influence of any friend of the moment was irresistible, and for that reason she drifted into the pleasure-seeking set in town.”
“But the tragedy?” Jevons exclaimed. “Tell us of that. My own inquiries show that you are aware of it all. Mrs. Courtenay murdered her husband, I know.”
“Mary——the assassin!” I gasped.
“Alas! it is too true. Now that my poor sister is dead, concealment is no longer necessary,” my love responded, with a deep sigh. “Mary killed her husband. She returned home, entered the house secretly, and, ascending to his room, struck him to the heart.”
“But the wound—how was it inflicted?” I demanded eagerly.
“With that pair of long, sharp-pointed scissors which used to be on poor Henry’s writing-table. You remember them. They were about eight inches long, with ivory handles and a red morocco case. The wound puzzled you, but to me it seems plain that, after striking the blow, in an endeavour to extricate the weapon she opened it and closed it again, thereby inflicting those internal injuries that were so minutely described at the inquest. Well, on that night I heard a sound, and, fearing that the invalid wanted something, crept from my room. As I gained the door I met Mary upon the threshold. She stood facing me with a weird, fixed look, and in her hand was the weapon with which she had killed her husband. That awful moment is fixed indelibly upon my memory. I shall carry its recollection to the grave. I dashed quickly into the room, and to my horror saw what had occurred. Then my thoughts were for Mary—to conceal her guilt. Whispering to her to obey me I led her downstairs, through the back premises, and so out into the street. A cab was passing, and I put her into it, telling the man to drive to the Hennikers’, with whom she had been spending the evening. Then, cleaning the scissors of blood by thrusting them several times into the mould of a garden I was passing, I crossed the road and tossed them over the high wall into the thick undergrowth which flanks Kew Gardens. At that spot I felt certain that they would never be discovered. As quickly as possible I re-entered the house, secured the door by which I had made my exit, and returned again to my room with the awful knowledge of my sister’s crime upon my conscience.”
“What hour was that?”
“When I retired again to bed my watch showed that it was barely half-past one. At two o’clock Short, awakened by his alarum clock, made the discovery and aroused the house. What followed you know well enough. I need not describe it. You can imagine what I felt, and how guilty was my conscience with the awful knowledge of it all.”
“The circumstances were certainly most puzzling,” I remarked. “It almost appears as though matters were cleverly arranged in order to baffle detection.”
“To a certain extent they undoubtedly were. I knew that the Hennikers would say nothing of poor Mary’s erratic return to them. I did all in my power to withdraw suspicion from my sister, at the risk of it falling upon myself. You suspected me, Ralph. And only naturally—after that letter you discovered.”
“But Mary’s homicidal tendency seems to have been carefully concealed,” I said. “I recollect having detected in her a strange vagueness of manner, but it never occurred to me that she was mentally weak. In the days immediately preceding the tragedy I certainly saw but little of her. She was out nearly every evening.”
“She was not responsible for her actions for several weeks together sometimes,” Sir Bernard interrupted. “I discovered it over a year ago.”
“And you profited by your discovery!” my love cried, turning upon him fiercely. “The crime was committed at your instigation!” she declared.
“At my instigation!” he echoed, with a dry laugh.
“I suppose you will say next that I hypnotised her—or some bunkum of that sort!”
