I would go to Lowhaven and stay at the same hotel. It might lead to something. In thinking the matter over I had arrived at the conclusion that I, having apparently no motive in young Gascoyne’s death, could use means which would be unwise on the part of people upon whom suspicion would fall as a natural consequence of their crime.

Supposing unseen I dropped aconite, or some such poison, into a whisky-and-soda, how could suspicion possibly fall on me? At any rate, it was worth while going to Lowhaven. I could not quite make up my mind whether to travel by the same train, or to precede them, or to follow them. Even such minor details required careful consideration. It was impossible to say which method of procedure might not leave a clue to the acute mind of Scotland Yard.

Discovering that there was only one hotel at Lowhaven, I decided to go down on the previous day.

Lowhaven turned out to be a mere village, at which I was somewhat sorry, as every new arrival became at once an object of attention. The hotel was situated at the extreme end of the tiny parade. Such walks as I took were all in the direction that led away from the town.

Whether I should write my own name in the hotel book or not was a question. I was undecided about it up to the last moment. I reflected that it was quite possible that a smart detective might take the trouble to find out all about the only visitor to the hotel if anything should occur. As a matter of fact, there were three other visitors in the hotel, a mother and two daughters, who as a rule kept to their rooms, only emerging to go for walks or drives.

Gascoyne and his companion did not come by the train they had settled on, and I began to wonder whether after all they had changed their minds and gone somewhere else, or whether circumstances had prevented their coming at all. I was far too cautious to ask or seek information even in the most round-about way.

I studied the time table in the privacy of my own room. There was another train which would bring them down about five o’clock.

I established myself in the vestibule with some afternoon tea in front of me, and a little after five they drove up looking deliciously happy.

I grew quite sentimental over them, and was compelled to take a long walk to cure myself.

I had, before I left town, decided that aconite would be the best thing I could use if I chose to run the risk of a poison which left evidences. Aconite essentially knows its own mind, and the struggle is not a long one.
