The dark days of the London winter brightened into spring, but the mystery of old Mr. Courtenay’s death remained an enigma inexplicable to police and public. Ambler Jevons had prosecuted independent inquiries assiduously in various quarters, detectives had watched the subsequent movements of Short and the other servants, but all to no purpose. The sudden disappearance of Short was discovered to be due to the illness of his brother.

The identity of the assassin, as well as the mode in which the extraordinary wound had been inflicted, both remained mysteries impenetrable.

At Guy’s we were a trifle under-staffed, and my work was consequently heavy; while, added to that, Sir Bernard was suffering from the effects of a severe chill, and had not been able to come to town for nearly a month. Therefore, I had been kept at it practically night and day, dividing my time between the hospital, Harley Street, and my own rooms. I saw little of my friend Jevons, for his partner had been ordered to Bournemouth for his health, and therefore his constant attendance at his office in Mark Lane was imperative. Ambler had now but little leisure save on Sundays, when we would usually dine together at the Cavour, the Globe, the Florence, or some other foreign restaurant.Whenever I spoke to him of the tragedy, he would sigh, his face would assume a puzzled expression, and he would declare that the affair utterly passed his comprehension. Once or twice he referred to Ethelwynn, but it struck me that he did not give tongue to what passed within his mind for fear of offending me. His methods were based on patience, therefore I often wondered whether he was still secretly at work upon the case, and if so, whether he had gained any additional facts. Yet he told me nothing. It was a mystery, he said—that was all.

Of Ethelwynn I saw but little, making my constant occupation with Sir Bernard’s patients my excuse. She had taken up her abode with Mrs. Henniker—the cousin at whose house Mary had stayed on the night of the tragedy. The furniture at Richmond Road had been removed and the house advertised for sale, young Mrs. Courtenay having moved to her aunt’s house in the country, a few miles from Bath.

On several occasions I had dined at Redcliffe Square, finding both Mrs. Henniker and her husband extremely agreeable. Henniker was partner in a big brewing concern at Clapham, and a very good fellow; while his wife was a middle-aged, fair-haired woman, of the type who shop of afternoons in High Street, Kensington. Ethelwynn had always been a particular favourite with both, hence she was a welcome guest at Redcliffe Square. Old Mr. Courtenay had had business relations with Henniker a couple of years before, and a slight difference had led to an open quarrel. For that reason they had not of late visited at Kew.

On the occasions I had spent the evening with Ethelwynn at their house I had watched her narrowly, yet neither by look nor by action did she betray any sign of a guilty secret. Her manner had during those weeks changed entirely; for she seemed perfectly calm and self-possessed, and although she alluded but seldom to our love, she treated me with that same sweet tenderness as before the fatal night of her brother-in-law’s assassination.

I must admit that her attitude, although it inspired me with a certain amount of confidence, nevertheless caused me to ponder deeply. I knew enough of human nature to be aware that it is woman’s mÉtier to keep up appearances. Was she keeping up an appearance of innocence, although her heart was blackened by a crime?

One evening, when we chanced to be left alone in the little smoking-room after dinner, she suddenly turned to me, saying:

“I’ve often thought how strange you must have thought my visit to your rooms that night, Ralph. It was unpardonable, I know—only I wanted to warn you of that man.”

“Of Sir Bernard?” I observed, laughing.

“Yes. But it appears that you have not heeded me,” she sighed. “I fear, Ralph, that you will regret some day.”

“Why should I regret? Your fears are surely baseless.”“No,” she answered decisively. “They are not baseless. I have reasons—strong ones—for urging you to break your connexion with him. He is no friend to you.”

I smiled. I knew quite well that he was no friend of hers. Once or twice of late he had said in that peevish snappy voice of his:

“I wonder what that woman, Mrs. Courtenay’s sister, is doing? I hear nothing of her.”

I did not enlighten him, for I had no desire to hear her maligned. I knew the truth myself sufficiently well.

But turning to her I looked straight into her dark luminous eyes, those eyes that held me always as beneath their spell, saying:

“He has proved himself my best friend, up to the present. I have no reason to doubt him.”

“But you will have. I warn you.”

“In what manner, then, is he my enemy?”

She hesitated, as though half-fearing to respond to my question. Presently she said:

“He is my enemy—and therefore yours.”

“Why is he your enemy?” I asked, eager to clear up a point which had so long puzzled me.

“I cannot tell,” she responded. “One sometimes gives offence and makes enemies without being aware of it.”

The evasion was a clever one. Another illustration of tactful ingenuity.

By dint of careful cross-examination I endeavoured to worm from her the secret of my chief’s antagonism, but she was dumb to every inquiry, fencing with me in a manner that would have done credit to a police-court solicitor. Though sweet, innocent, and intensely charming, yet there was a reverse side of her character, strong, firm-minded, almost stern in its austerity.

I must here say that our love, once so passionate and displayed by fond kisses and hand-pressing, in the usual manner of lovers, had gradually slackened. A kiss on arrival and another on departure was all the demonstration of affection that now passed between us. I doubted her; and though I strove hard to conceal my true feelings, I fear that my coldness was apparent, not only to her but to the Hennikers also. She had complained of it when she called at my rooms, and certainly she had full reason for doing so. I am not one of those who can feign love. Some men can; I cannot.

Thus it will be seen that although a certain coolness had arisen between us, in a manner that seemed almost mutual, we were nevertheless the best of friends. Once or twice she dined with me at a restaurant, and went to a play afterwards, on such occasions remarking that it seemed like “old times,” in the early days of our blissful love. And sometimes she would recall those sweet halcyon hours, until I felt a pang of regret that my trust in her had been shaken by that letter found among the dead man’s effects and that tiny piece of chenille. But I steeled my heart, because I felt assured that the truth must out some day.Mine was a strange position for any man. I loved this woman, remember; loved her with all my heart and with all my soul. Yet that letter penned by her had shown me that she had once angled for larger spoils, and was not the sweet unsophisticated woman I had always supposed her to be. It showed me, too, that in her heart had rankled a fierce, undying hatred.

Because of this I did not seek her society frequently, but occupied myself diligently with my patients—seeking solace in my work, as many another professional man does where love or domestic happiness is concerned. There are few men in my profession who have not had their affairs of the heart, many of them serious ones. The world never knows how difficult it is for a doctor to remain heart-whole. Sometimes his lady patients deliberately set themselves to capture him, and will speak ill-naturedly of him if he refuses to fall into their net. At others, sympathy with a sufferer leads to a flirtation during convalescence, and often a word spoken in jest in order to cheer is taken seriously by romantic girls who believe that to marry a doctor is to attain social status and distinction.

Heigho! When I think of all my own little love episodes, and of the ingenious diplomacy to which I have been compelled to resort in order to avoid tumbling into pitfalls set by certain designing Daughters of Eve, I cannot but sympathise with every other medical man who is on the right side of forty and sound of wind and limb. There is not a doctor in all the long list in the medical register who could not relate strange stories of his own love episodes—romances which have sometimes narrowly escaped developing into tragedies, and plots concocted by women to inveigle and to allure. It is so easy for a woman to feign illness and call in the doctor to chat to her and amuse her. Lots of women in London do that regularly. They will play with a doctor’s heart as a sort of pastime, while the unfortunate medico often cannot afford to hold aloof for fear of offending. If he does, then evil gossip will spread among his patients and his practice may suffer considerably; for in no profession does a man rely so entirely upon his good name and a reputation for care and integrity as in that of medicine.

I do not wish it for a moment to be taken that I am antagonistic to women, or that I would ever speak ill of them. I merely refer to the mean method of some of the idling class, who deliberately call in the doctor for the purpose of flirtation and then boast of it to their intimates. To such, a man’s heart or a man’s future are of no consequence. The doctor is easily visible, and is therefore the easiest prey to all and sundry.

In my own practice I had had a good deal of experience of it. And I am not alone. Every other medical man, if not a grey-headed fossil or a wizened woman-hater, has had similar episodes; many strange—some even startling.

Reader, in this narrative of curious events and remarkable happenings, I am taking you entirely and completely into my confidence. I seek to conceal nothing, nor to exaggerate in any particular, but to present the truth as a plain matter-of-fact statement of what actually occurred. I was a unit among a hundred thousand others engaged in the practice of medicine, not more skilled than the majority, even though Sir Bernard’s influence and friendship had placed me in a position of prominence. But in this brief life of ours it is woman who makes us dance as puppets on our miniature stage, who leads us to brilliant success or to black ruin, who exalts us above our fellows or hurls us into oblivion. Woman—always woman.

Since that awful suspicion had fallen upon me that the hand that had struck old Mr. Courtenay was that soft delicate one that I had so often carried to my lips, a blank had opened in my life. Consumed by conflicting thoughts, I recollected how sweet and true had been our affection; with what an intense passionate love-look she had gazed upon me with those wonderful eyes of hers; with what wild fierce passion her lips would meet mine in fond caress.

Alas! it had all ended. She had acted a lie to me. That letter told the bitter truth. Hence, we were gradually drifting apart.

One Sunday morning in May, just as I had finished my breakfast and flung myself into an armchair to smoke, as was my habit on the day of rest, my man entered, saying that Lady Twickenham had sent to ask if I could go round to Park Lane at once. Not at all pleased with this call, just at a moment of laziness, I was, nevertheless, obliged to respond, because her ladyship was one of Sir Bernard’s best patients; and suffering as she was from a malignant internal complaint, I knew it was necessary to respond at once to the summons.

On arrival at her bedside I quickly saw the gravity of the situation; but, unfortunately, I knew very little of the case, because Sir Bernard himself always made a point of attending her personally. Although elderly, she was a prominent woman in society, and had recommended many patients to my chief in earlier days, before he attained the fame he had now achieved. I remained with her a couple of hours; but finding myself utterly confused regarding her symptoms, I resolved to take the afternoon train down to Hove and consult Sir Bernard. I suggested this course to her ladyship, who was at once delighted with the suggestion. Therefore, promising to return at ten o’clock that night, I went out, swallowed a hasty luncheon, and took train down to Brighton.

The house was one of those handsome mansions facing the sea at Hove, and as I drove up to it on that bright, sunny afternoon, it seemed to me an ideal residence for a man jaded by the eternal worries of a physician’s life. The sea-breeze stirred the sun-blinds before the windows, and the flowers in the well-kept boxes were already gay with bloom. I knew the place well, for I had been down many times before; therefore, when the page opened the door he showed me at once to the study, a room which lay at the back of the big drawing-room.“Sir Bernard is in, sir,” the page said. “I’ll tell him at once you’re here,” and he closed the door, leaving me alone.

I walked towards the window, which looked out upon a small flower garden, and in so doing, passed the writing table. A sheet of foolscap lay upon it, and curiosity prompted me to glance at it.

What I saw puzzled me considerably; for beside the paper was a letter of my own that I had sent him on the previous day, while upon the foolscap were many lines of writing in excellent imitation of my own!

He had been practising the peculiarities of my own handwriting. But with what purpose was a profound mystery.

I was bending over, closely examining the words and noting how carefully they had been traced in imitation, when, of a sudden, I heard a voice in the drawing-room adjoining—a woman’s voice.

I pricked my ears and listened—for the eccentric old fellow to entertain was most unusual. He always hated women, because he saw too much of their wiles and wilfulness as patients.

Nevertheless it was apparent that he had a lady visitor in the adjoining room, and a moment later it was equally apparent that they were not on the most friendly terms; for, of a sudden, the voice sounded again quite distinctly—raised in a cry of horror, as though at some sudden and terrible discovery.

“Ah! I see—I see it all now!” shrieked the unknown woman. “You have deceived me! Coward! You call yourself a man—you, who would sell a woman’s soul to the devil!”

“Hold your tongue!” cried a gruff voice which I recognised as Sir Bernard’s. “You may be overheard. Recollect that your safety can only be secured by your secrecy.”

“I shall tell the truth!” the woman declared.

“Very well,” laughed the man who was my chief in a tone of defiance. “Tell it, and condemn yourself.”
