The enigma was maddening; I felt that sooner or later its puzzling intricacies must induce mania in some form or other. Insomnia had seized me, and I had heard that insomnia was one of the most certain signs of approaching madness. In vain I had striven to penetrate the mystery of my union and its tragic sequel, at the same time leaving undisturbed that cold, emotionless mask which I had schooled myself to wear before the world.

Days had passed since my visit to Eaton Square, and through all my pain the one thought had been dominant—I must obtain from Dora the revelation she had promised. It seemed that blindly, willingly I had resigned every hope, joy, and sentiment that made life precious; I had, like Faust, given my soul to the Torturer in exchange for a few sunny days of bliss and fleeting love-dreams.

Wearied, despondent, and anxious I lived through those stifling hours with but one thought, clinging tenaciously to one hope; yet after all, what could I expect of a woman whose mind was affected, and whose lover accused of a capital offence? In this distracted mood I was wandering one evening along the Strand and arriving at Charing Cross Station turned in mechanically to purchase a paper at the bookstall. The hands of the great clock pointed to half-past eight, and the continental train stood ready to start. Porters who had wheeled mountains of luggage stood, wiped their brows and pocketed the tips of bustling tourists about to commence their summer holiday. City clerks in suits of cheap check and bearing knapsacks and alpenstocks were hurrying hither and thither, excited over the prospect of a fortnight in Switzerland for a ten-pound note, while constant travellers of the commercial class strode leisurely to their carriages smoking, and ladies already seated peered out anxiously for their husbands. The scene is of nightly occurrence after the London season, when everyone is leaving town, and I had witnessed it many times when I, too, had been a passenger by the night mail. As I stood for a moment watching I heard two men behind me engaged in excited conversation in French.

“I tell you it’s impossible,” exclaimed one in a decisive tone.

“Very well, then, you shall not leave London,” the other said, and as I turned I was surprised to find that one of them was Markwick, the other a short, rather elderly, shabbily-dressed little Frenchman, whose grey beard and moustache were unkempt, whose silk hat was sadly rubbed and whose dark eyes were keen and small. In an attitude of firm determination he held Markwick by the arms and glared for a moment threateningly into his face. The latter, too occupied to notice my presence, retorted angrily—

“Let me go, you fool. You must be mad to act like this, when you know what we both have at stake.”

“No, no,” the irate Frenchman cried. “No, I am not mad. You desire to escape, but I tell you that you shall not unless you give me the money now, before you go.”

“How much, pray?” Markwick asked with a dark, severe look.

“What you promised. One thousand pounds. Surely it is not a great price.”

“You shall have it to-morrow—I’ll send it to you from Paris.”
