Tracks in the Snow by Godfrey R. Benson — Read

Here let me mention that I have fancied since that I recognised the ill-looking foreigner who was with me at the inn and in the train. I recognised him in a chemist's shop in a very fashionable shopping street. I think it would be libellous to name the street. The telegraphic address which my wife sent to Callaghan was the telegraphic address of that fashionable chemist's shop.

I had intended to take leave of Callaghan for the time upon our arrival at the station, but I found that this was not to be done, for Callaghan was determined to obey almost to the letter my wife's behest to him, not to leave me. He took me to luncheon at a restaurant, and then prevailed upon me to come with him by one of our fast trains to my own house, collect there all the papers which I possessed bearing on the affair of Peters, and bring them to his chambers, where he was resolved I should at present stay.
