“Could you not follow it?”
“Excellent, Watson! You are scintillating this evening. The idea did cross my mind. There is, as you may have observed, a bicycle shop next to our inn. Into this I rushed, engaged a bicycle, and was able to get started before the carriage was quite out of sight. I rapidly overtook it, and then, keeping at a discreet distance of a hundred yards or so, I followed its lights until we were clear of the town. We had got well out on the country road, when a somewhat mortifying incident occurred. The carriage stopped, the doctor alighted, walked swiftly back to where I had also halted, and told me in an excellent sardonic fashion that he feared the road was narrow, and that he hoped his carriage did not impede the passage of my bicycle. Nothing could have been more admirable than his way of putting it. I at once rode past the carriage, and, keeping to the main road, I went on for a few miles, and then halted in a convenient place to see if the carriage passed. There was no sign of it, however, and so it became evident that it had turned down one of several side roads which I had observed. I rode back, but again saw nothing of the carriage, and now, as you perceive, it has returned after me. Of course, I had at the outset no particular reason to connect these journeys with the disappearance of Godfrey Staunton, and was only inclined to investigate them on the general grounds that everything which concerns Dr. Armstrong is at present of interest to us, but, now that I find he keeps so keen a look-out upon anyone who may follow him on these excursions, the affair appears more important, and I shall not be satisfied until I have made the matter clear.”
