I have never been able satisfactorily to account for the adventure which befell me as I strolled through St. James’s Park on my way to Victoria. Whether I was the subject of an attack by a mere footpad, or by some tool of our enemies who knew of my work and mission, I cannot say. But one of those strange premonitions, which come so frequently to men who, like myself, carry their lives in their hands, as all spies do, undoubtedly saved my life.

Since I left Madame Gabrielle the weather had changed. Heavy clouds had rolled up, as if a storm were threatening, and it had grown very dark. Having time to spare, I had intentionally made a détour from my direct road, and I was in a lonely pathway when something, I know not what, made me suddenly face round, with every nerve and muscle braced for instant action.

I was only just in time. From the grass at the side of the pathway a man leaped at me. In the gloom I caught sight of his upraised arm and the flash of a knife.

It is hard to catch the practised student of jiu-jitsu unawares, and that fascinating form of self-defence has been one of my special hobbies. Like a flash I jumped in to meet the charge of my assailant. Before his knife could descend my right arm was crooked into his and I had his wrist in the grip of my left hand. Flinging my whole weight forward, I wrenched his right arm savagely backward and downward. With a half-stifled scream of pain the man toppled over backward, his head striking the ground with a crash that left him senseless.

Here was a pretty coil! I dared not wait to give the man into custody, for that would have meant police inquiries and endless publicity, to say nothing of missing my train and a fatal delay to my important mission. And just now I could not afford publicity. So I decided to leave him alone, to take his chance and make his own explanation, if necessary. Picking up his knife, I thrust it deeply into a flower-bed, and, stamping it well down with my heel, hurried on to the station, and was soon on my way to France. Who and what my assailant was I never heard. But I pondered over the incident a good deal on my journey, for it may have meant that my mission was already known. Still, this was unlikely, so I merely decided to keep an extra sharp look-out.

On Friday, at the hour I had appointed with Madame Gabrielle, I passed the barrier and walked along the platform of the Orleans station in Paris, where in the summer twilight the express, with its powerful, constantly exploding locomotive, stood ready for the long run across France to the Spanish frontier. I bought a copy of Le Soir at the bookstall, and while doing so my eye fell on a rather shabbily-dressed, insignificant-looking little man who apparently was lounging absently about.

Every “natural” spy, if I may use the term—and I think I am one of them—possesses a large measure of that intuition which is somewhat akin to a woman’s power of frequently jumping to a perfectly correct conclusion without the trouble of logically working a problem out. The things which matter in our calling are often seemingly the most trivial. There was nothing about this shabby little stranger to call particular attention to him, yet from the moment I saw him I felt instinctively that in some way my lot and his were bound up together. And, try as I would, I was unable to shake off that feeling.

How far I was correct the sequel will show.

As I entered the train I saw Madame Gabrielle, carrying her dressing-bag and followed by a porter with her hand luggage, pass the window of my compartment and enter a first-class carriage nearer the front of the train. Her eyes met mine as she passed, but she gave no sign of recognition. Of the little shabby man I saw nothing, though I kept a sharp look-out, and I concluded at last that he had left the platform.

All through that night the train roared onward by way of Orleans and Tours down to Bordeaux. I slept, as I usually do, but dreamed in a manner quite unusual with me. Throughout the night my sleeping thoughts were harassed by that shabby little man who had, I seemed to feel no doubt, witnessed my departure with a perfectly definite object.
