The next day and the next passed uneventfully. Eagerly I scanned the papers morning and evening to ascertain whether Jack had been arrested, but there was no news of the fact, and I began to believe that my friend had after all succeeded in eluding the vigilance of the police. That he was guilty I could not doubt. Dora’s words were but passionate utterances, such as might have been expected of a woman who loves an accused man. Indeed, as time went by I reproached myself for my egregious folly in giving her declaration credence and listening to it attentively. It was, however, impossible to let the matter stand as she had left it. Her mention of my lost well-beloved had whetted my curiosity, and some further inquiry must take place, although I saw that so long as she remained in her present state I could do nothing.

Impatient, with head full of cogent arguments I had raised against myself, I waited in agony of mind indescribable. I lived for one purpose alone, to solve the inscrutable mystery.

A discovery I made accidentally struck me as curious. One afternoon, while in the Park, I saw Fyneshade and his wife driving together. Sitting beside her husband, with an expression of perfect contentment and happiness, Mabel’s attention had been attracted in the opposite direction, therefore she did not notice me. That there had been a reconciliation was apparent, and it gave me intense satisfaction, for I knew that no questions would now be asked me regarding that clandestine meeting in the grounds of Blatherwycke.

Curiously enough, on the following day I received an invitation from Mabel to dine en famille at Eaton Square, and believing that she had some strong motive in this I accepted.

The meal was served with stateliness even though the Earl and his wife had no other visitor. It had been a breathless day in London, and was still light when dinner ended and Mabel rose and left us. The eastern sky was growing from blue to a violet dusk, and even then the crimson-shaded candles upon the table were merely ornamental.

We had been smoking and gossiping some time, and as I sat opposite my host I thought I somehow observed a change in him. Some anxiety seemed reflected in his clear-cut features, the expression upon which was a trifle stern and moody. It had softened a little while his wife kept up her light amusing chatter, but when she left there again settled upon his countenance the troubled look that puzzled me. It was caused no doubt by his suspicions of Mabel’s faithlessness.

He had been describing a new play he had seen produced in Paris, when suddenly he turned to me, exclaiming, as he wiped his single eye-glass and readjusted it: “Dora’s illness is most unfortunate, isn’t it? The whole thing seems enshrouded in mystery. Even Mabel is either ignorant, or desires to keep the cause of her sister’s affliction a secret. What do you know about it?”

I removed my cigar from my lips very slowly, for I hesitated whether I should unbosom myself and explain the strange circumstances in which I had discovered her. But in that brief moment I saw that if I did so I might become an unwilling witness in the tragedy. I knew the Earl as an inveterate gossip at his club, and having no desire that my name should be bruited all over London in connection with the affair, I therefore affected ignorance.

He plied me with many questions regarding Bethune’s movements, but to these also I remained dumb, for I could detect the drift of his conversation.

“Well,” he said at length, “he killed young Sternroyd undoubtedly, though from what motive it is impossible to imagine.”
