Of course, it was quite within the bounds of possibility that the false Professor might use yet another name if he wished to avoid being followed from Edinburgh. Besides, I had noticed that just as at the North British at Edinburgh, so here, telegrams were exhibited upon a board, and could be taken. Therefore, if a wire came in the name of Martin, he could quite easily claim it.

After a wash I wandered about the hotel, through the lounge, smoking-room, and the other of the public apartments. Yet how could I recognise a man who was disguised, and whom I had never seen?

I was placed at a disadvantage from the very first by never having met this man who had posed as the dead Professor. Yet with the knowledge that Kirk desired particularly to see him, I felt that there was a probability of their meeting, and that, if only I remained wary and watchful, I should come across, amid the hundreds of persons staying there, the mysterious dweller in Bedford Park.

From my arrival at eleven till half-past one I remained on the alert, but saw no one I knew. Therefore I retired to bed, thoroughly worn-out by that constant vigil. Yet I was in no way disheartened. The false Professor had started from Edinburgh for that destination, and was, I felt confident, staying there under another name. It only lay with me to unmask him, or to wait until the pair met clandestinely, and then to demand to know the truth.

Surely in all the annals of crime there had never been one so surrounded by complex circumstances as the tragedy of Sussex Place, and assuredly, too, no innocent man had been more ingeniously misled than my unfortunate self.

Next day, from eight o’clock in the morning till late at night, I idled about the big hotel, ever anxious and ever watchful. I kept an eye upon each arrival and each departure.

Then I became slowly and against my will, convinced that the false Professor had not come to that hotel, but had put up somewhere else, well knowing that he could obtain the telegraphic message from Kirk whenever he cared to step in and take it from the board.

Again, even though at the heels of the conspirators, was I yet being outwitted—a fact which became the more impressed upon me on the third day of my futile expectancy.

Hourly I watched that telegraph-board, intending to annex quietly any message addressed to Martin, and act upon any appointment it contained.

But, alas! my watchfulness remained unrewarded.
