Then came the 2.20 p.m. from Charing Cross to Folkestone, and so to Boulogne, Amiens and the rest, travelling the same road as the Engadine express. This was the last of the day service, as it gave most time, allowing people to start at the very latest moment, and I felt it quite probable that my lady would prefer to take it.

I reached Amiens a little before 5 p.m., and I had a wait of half an hour for the first express from Calais. I was greatly disappointed when at last it appeared issuing from the tunnel, and passed me where I stood at the commencement of the platform, taking stock of each carriage as it passed. The train seemed to be quite empty; there were no passengers, so the officials, the conductors, informed me when I talked to them, sad and unhappy at the certain loss of tips. Only one of them had any luck, Jules l'Echelle, of the Lucerne sleeping-car, who had one or two people on board.

I questioned him not very hopefully, but was agreeably surprised when he told me that his clients consisted of two ladies with a child, and one gentleman. English? Yes, all English. The lady, quite a lady, a grande dame belle personne, tall, fine figure, well dressed; her companion no doubt her servant; the child, well, an ordinary child, an infant in arms. What would you?

I had them, I felt sure. There could be no mistaking this description. I held them in the hollow of my hand. Here they were in this car, and it would be all my own fault if they escaped me. It would be necessary only to verify my conclusions, to identify the lady according to the description and photograph given me. For the rest I knew what to do.

But now a quite unexpected difficulty turned up.

As I have said, there was one other passenger, a gentleman, in the car, and I felt it would be prudent to make his acquaintance. No doubt I could tell at the first glance whether or not he was an ordinary traveller, or whether he was a friend and accomplice of the lady under observation.

I regret to say that he met me in a very hostile spirit. I was at great pains to be affable, to treat him with all the courtly consideration I have at command, and I flatter myself that in the matter of tact and good-breeding I do not yield to princes of the blood royal. But my civility was quite thrown away. The man was an absolute brute, abrupt, overbearing, rude. Nothing would conciliate him. I offered him a cigar (a Borneo of the best brand, at 10s. the hundred), and he not only refused it, but positively forbade me to smoke. There were ladies in the carriage, he said (this was the first reference made to them), and, when declining to be ordered about, I proposed to refer the question to themselves, he threw himself violently upon me and assaulted me brutally.

Fortunately the attendant came to my rescue or I should have been seriously injured. He lifted me into my compartment very kindly, and acted like an old friend, as indeed he was, for I remembered him as the Jules l'Echelle with whom I served some time back as an assistant at the Baths of Bormio.

It was, of course, clear to my mind that my assailant was associated in some way with the lady, and probably a confederate. I saw that I must know more about him, with the least possible delay, and as soon as Jules had left me, promising to return later and talk of old times, and the changes that had come over us since then, I ventured to look out and get a glimpse of the other man, I will not call him gentleman after his conduct.

He was nowhere in sight, but I could hear his voice, several voices, talking together at the far end. No doubt he had joined his friends in their compartment, and the moment seemed opportune to visit his. It was next to mine, and the door stood invitingly open. A few minutes, seconds even, would be enough to tell me something of his identity, perhaps all I wanted to.
