True, there was a queer, insignificant-looking old lady in rusty black, who had been on the platform when I had arrived, who had crossed the bridge and waited for the train from Plymouth, and who was now making her way back into Totnes in the direction we were walking.

Could it be possible that he feared her?

It struck me that he might have recognised that I had travelled there to meet him in place of the man now deceased; therefore I hurried on and got in front so that he might, if he so wished, follow me to the Seymour Hotel.

But judge my chagrin when at last we entered the main street, and while I turned down towards the bridge, he turned in the opposite direction, thus showing that he had not detected my anxiety to speak with him. And the old lady had followed in his footsteps.

Suddenly a thought occurred to me. It was surely more than probable that Mr Dawnay was there to meet the man Arnold, in ignorance of his death. Therefore, having allowed him to get on some distance, I turned upon my heel and followed him.

His movements were certainly curious. He was undoubtedly avoiding the unwelcome attentions of the old lady, who now seemed to be acting in conjunction with a dark-haired, middle-aged man with beetling brows, who wore a shabby brown suit and a last year’s straw hat.

The man with the red cravat entered an inn in Fore Street, and remained there a full hour, the other man watching in the vicinity. Then, on emerging, he went to a chemist’s, and afterwards turned his footsteps back towards the station.

I saw that his intention was to leave Totnes. Therefore, in preference to following on foot, I drove to the station in a fly.

He had never once removed those grey suède gloves, though the day was so hot, for on the up-platform the man in the straw hat was still idling behind him. A number of people were waiting for the train, and I, discerning Mr Dawnay’s intention of travelling, entered the booking-office and bought a ticket for Exeter.

At last the London express came roaring into the station, when the man whom I was there to meet quickly entered a first-class corridor compartment, and while I remained vigilant, I saw the mysterious watcher enter a carriage a little way behind. Then, just as the train was leaving, I sprang into the compartment next that of Mr Dawnay.
