"Good evening!" I shouted, and the next instant the engine had started, and I was in my saddle.

Even then my pursuer had got up so much speed that he must surely have caught me had he not stopped to make inquiry of my late acquaintance. I was rounding a corner at the moment, and so was able to glance over my shoulder and see what was happening. The cyclist was then in the act of remounting, and I noted that he was in very dark clothes. It might or might not have been a uniform, but I fancied it was. Anyhow, I felt peculiarly little enthusiasm for making his acquaintance.

On I sped, working rapidly up to forty miles an hour, and quite careless now of any little sensation I might cause. I had sensations myself, and did not grudge them to other people. The road quickly left the coast and turned directly inland, and presently it began to wind along the edge of a long reedy stretch of water, with a steep bank above it on the other side. The windings gave me several chances of catching a glimpse of my pursuer, and I saw that I was gaining nothing; in fact, if anything he was overhauling me.

"I'll try them!" I said to myself.

"Them" were nails. Wiedermann had done me no more than justice in assuming I had come well provided against possible contingencies. Each of my side-pockets had a little packet of large-headed, sharp-pointed nails. I had several times thrown them experimentally on the floor of my cabin, and found that a gratifying number lay point upwards. I devoutly prayed they would behave as reasonably now.

This stretch of road was ideal for their use—narrow, and with not a house to give succour or a spectator to witness such a very suspicious performance, I threw a handful behind me, and at the next turn of the road glanced round to see results. The man was still going strong. I threw another handful and then a third, but after that the road ran straight for a space, and it was only when it bent to the right round the head of the loch that I was able to see him again. He had stopped far back, and was examining his tyres.

The shadows by this time were growing long, but there were still some hours before darkness would really shelter me, and in the meantime what was I to do with myself, and where to turn? Judging from the long time that had elapsed between my discovery in the early morning and the appearance of this cyclist at the very place which I had thought would be the last where they would seek me, the rest of the island had probably been searched and the hue and cry had died down by this time. So for some time I ought to be fairly safe anywhere: until, in fact, my pursuer had reached a telegraph office, and other scouts had then been collected and sent out. And if my man was an average human being, he would certainly waste a lot of precious time in trying to pump up his tyres or mend them before giving it up as a bad job and walking to a telegraph office.

That, in fact, was what he did, for in this open country I was able a few minutes later to see him in the far distance still stopping by that loch shore. But though I believe in trusting to chance, I like to give myself as many chances as possible. I knew where all the telegraph offices were, and one was a little nearer him than I quite liked. So half a mile farther on, at a quiet spot on a hill, I jumped off and swarmed up one of the telegraph-posts by the roadside, and then I took out of my pocket another happy inspiration. When I came down again, there was a gap in the wire.

There was now quite a good chance that I might retain my freedom till night fell, and if I could hold out so long as that—well, we should see what happened then! But what was to be done in the meantime? A strong temptation assailed me, and I yielded to it. I should get as near to my night's rendezvous as possible, and try to find some secluded spot there. It was not perhaps the very wisest thing to risk being seen there by daylight and bring suspicion on the neighbourhood where I meant to spend two or three days; but you will presently see why I was so strongly tempted. So great, in fact, was the temptation that till I got there I hardly thought of the risk.

I rode for a little longer through the same kind of undulating, loch-strewn inland country, and then I came again close to the sea. But it was not the open sea this time. It was a fairly wide sound that led from the ocean into a very important place, and immediately I began to see things. What things they were precisely I may not say, but they had to do with warfare, with making this sound about as easy for a hostile ship to get through, whether above the water or below, as a pane of glass is for a bluebottle. As I rode very leisurely, with my head half turned round all the while, I felt that my time was not wasted if I escaped safely, having seen simply what I now noted. For my eye could put interpretations on features that would convey nothing to the ordinary traveller.
