I was prepared to be watched on the way from Blackwater Park to the station, exactly as I had been watched in London the day before. But I could not discover at the time, whether I was really followed on this occasion or not. The man in black might have had means of tracking me at his disposal of which I was not aware, but I certainly saw nothing of him, in his own person, either on the way to the station, or afterwards on my arrival at the London terminus in the evening. I reached home on foot, taking the precaution, before I approached our own door, of walking round by the loneliest street in the neighbourhood, and there stopping and looking back more than once over the open space behind me. I had first learnt to use this stratagem against suspected treachery in the wilds of Central America⁠—and now I was practising it again, with the same purpose and with even greater caution, in the heart of civilised London!

Nothing had happened to alarm Marian during my absence. She asked eagerly what success I had met with. When I told her she could not conceal her surprise at the indifference with which I spoke of the failure of my investigations thus far.
