And as I stood there I wondered whether after all Jeanjean had actually recognized me when we met in Church Square—or whether he had been struck merely by what he deemed a chance resemblance, and had passed me by without further thought.

Had he recognized me I do not think he would have dared to remain in Cromer a single hour. Hence, I hoped he had not. The fact would render my work of investigation a thousandfold easier.

Presently, after a full quarter of an hour's conversation, the pair strolled together along the moonlit road back towards the town, which at that hour was wrapped in slumber.

By a circuitous route they reached the narrow street at the back of the house where old Mr. Gregory and his nephew had lived, and, after passing and repassing it several times, returned by the way they had come.

Near the railway bridge, where Jeanjean had first met the stranger, both paused and had another earnest conversation. More than once in the lamplight I had caught sight of the man's face, a keen face, with dark moustache, and sharp, dark eyes. He had a quick, agile gait, and I judged him to be about eight-and-twenty.

Presently the two walked out beyond the arch, and I saw the younger man go behind a hedge, from which he wheeled forth a motor-cycle that had been concealed there. They bade each other adieu, and then, starting his engine, the stranger mounted the machine, and next moment was speeding towards Norwich without having lit his lamp, possibly having forgotten to do so in his hurry to get away.

The Frenchman watched his friend depart, then, leisurely lighting a cigarette, turned and went back to the house in Overstrand Road where he had taken up his temporary abode.

It was half-past two when the night-porter at the Hôtel de Paris admitted me, and until the sun had risen over the sea, I sat at my open window, smoking, and thinking.

The discovery that Jules Jeanjean was in that little East Coast town was to me utterly amazing. What was his business in Cromer?
