I loved her with all my heart, and had believed implicitly that she reciprocated my affection, yet here, in this single moment, the cup of happiness was dashed from my lips. I knew I had been the victim of base deception. While I, fool that I had been, had fondly imagined that she loved me; she had abandoned all self-respect and allowed herself to walk in a public garden with a chance-met acquaintance. Sonia’s ominous words recurred to me, and I saw how I had been tricked and betrayed. The pretty refugee was right, notwithstanding the denunciations of the diplomatist and the spy, both of whom had some motive in discrediting her statements.

With eager eyes and heavy heart I followed the pair cautiously, fearing each moment lest either should turn and detect my presence. Apparently they were too deeply engrossed in each other’s talk, which, although carried on in a tone so low that I could catch no single word, seemed scarcely of an amatory nature, judging from the man’s gestures. To me it appeared rather as if he were urging her to do something from which she shrank. Once, while he spoke, she stopped short and stretched out both hands towards him in an attitude of supplication. But he did not heed her, for, giving vent to a low laugh, he continued, emphasising his words as before. Then, clenching her hands, she stamped her foot in anger, and tossing her head in contempt, walked forward again, heedless of her companion’s threatening attitude.

From that moment both grew calmer, for the man, uttering words of forgiveness, snatched up her hand and imprinted a kiss upon it. For a brief second she allowed her hand to linger in his grasp, then withdrew it gently, but firmly, regarding him with earnestness the while. This action aroused my anger to a fierce, murderous hatred. With difficulty I managed to preserve an outward calm, because, in my state of mind, I felt compelled to watch and wait. Yet, if I had had a weapon ready to my hand at that moment, I verily believe that I must have thrown myself upon this arrogant cad, and mercilessly killed him.

The manner in which his hat was set upon his head, slightly askew, in the manner of the London “’Arry,” and his over-burdening mannerism, were in themselves sufficient to show the type of lover my wife cultivated. As I stepped softly behind them in the gloom, I told myself that she must leave my house that night, or I should. I felt in my throat a choking sensation, for I had loved her so fervently that this discovery of her falseness had utterly unnerved me, and even in those moments of fierce anger and hatred I confess that tears welled in my eyes. Ella was the only woman I had ever loved, yet she who had taken her marriage vows only a few short months before had already discarded me for this overdressed idiot, who would be termed in vulgar parlance a “bounder.”

Perhaps he did not know her to be married. This thought took possession of me. When their quarrel ended it became manifest that Ella herself was endeavouring to fascinate and hold him, just as she had charmed me, by the softness of her speech, her exquisite grace, and her wonderful beauty. She spoke quietly, with her dainty finger-tips laid lightly upon his arm, while he listened, gazing earnestly into her face, enchanted.

To-night, I told myself, the bonds uniting me to Ella should be for ever severed. I remembered the many occasions when she had been absent, visiting imaginary friends; I recollected the evening she brought home the violets and preserved them carefully in water until they smelt so faint that she was compelled to throw them away; I had not forgotten the fact that blades of grass did not grow in the squalid, overcrowded streets of modern Camberwell. I glanced around at the grass on every side. Perhaps she frequented that place, and took clandestine walks daily with her lover beneath those leafless trees. The thought provoked my bitter hatred, and I know not how I refrained from facing the pair. I managed, however, to hold myself back, watching them exchange a tender farewell at the gate that led into Kensington High Street, next the Palace Hotel, and while the man raised his hat politely and, turning, walked away in the direction of Knightsbridge, Ella, her face radiant and happy, bowed and set out homeward in the opposite direction.

Beneath the lamp in the gateway I had, in those brief seconds, obtained a glimpse of his face. It was that of a young man of about two-and-twenty, with strongly marked features, fair-haired, and of quite a different type than I had conjectured. The features were rather refined, by no means those of a cad, but rather those of a well-bred young idler, who affected the dress and manners of that class of youths who frequent the Café Monico on Sunday evenings, the slaves of the counter.

Once he glanced back to Ella, but she did not turn; then he went on and was lost in the darkness, while I followed my wife’s neat figure through the bustling throng of foot-passengers.
