The whole affair formed a complete enigma. Perhaps I had acted very foolishly in mixing myself up with a perfect stranger, and as day succeeded day this thought became the more and more impressed upon me.

I suppose in order that you should understand matters aright I ought here to say something concerning myself.

I, Lionel Kemball, was aged twenty-seven. My father, a well-known London surgeon, who had been knighted for his services in the interests of surgical science, had died two years ago, leaving me with a comfortable old house, called Upton End, near Newport Pagnell, in Buckinghamshire, and an income of about a couple of thousand a year. Three years prior to his death he had retired and given up the house in Cavendish Square, preferring life in healthier and quieter surroundings. I had studied medicine, and had passed my preliminary examinations at Edinburgh, when I found myself troubled slightly with my lungs, and had been advised to take a trip to Australia. To my satisfaction I had returned in the very pink of health and perfectly cured.

I had visited Ceylon, the cities of Sydney, Brisbane, and Perth, had witnessed some of the wonders of New Zealand, and now, on my return, had become involved in this most curious and perplexing romance.

The day on which I opened Mr Arnold’s strange letter was the 8th of June, therefore twelve days had to elapse before I could go down to Devonshire to meet the mysterious Mr Dawnay.

Those were hot, exciting days. Such blazing weather in June had not been experienced in London for years. It was hot by day, succeeded by oppressive, breathless evenings, with that red dust-haze seen only in our great metropolis. The Derby had been run and London hotels were crammed. The colossal Cecil, at which it was my habit to stay, was filled to overflowing by crowds of Americans, and the West End ran riot with gaiety and extravagance, as it always does each season.

Perhaps fortunately for me, for it prevented my mind being too much concentrated upon my remarkable trust, I found myself involved in some trouble concerning some land down at Upton End, and I had a number of interviews with my late father’s solicitors. A lawsuit was threatened, and it looked much as though I should be the loser by several hundreds a year.

My mother died when I was but ten, and though I was fond of a country life, yet, somehow, since my father’s decease, I had not cared for the loneliness and solitude of the quaint old house. It was certainly a delightful old place, with several oak-panelled chambers, and clinging to it were all sorts of quaint legends of Roundheads and Cavaliers. Its old bowling-green and its gardens ablaze in summer with crimson ramblers were charming; yet it was, after all, only a white elephant to me, a bachelor. So I had kept on a couple of the old servants, who together with Tucker, the head-gardener, and his assistant, kept the place going—for I had secret thoughts of letting it furnished.

My trouble over the ownership of the piece of land forming a portion of the farm attached to the house, and several other matters which had been neglected owing to my absence in Australia, kept my hands pretty full; nevertheless, I found time one evening to take a taxi up to Highgate Cemetery in order to see that the grave of my dead friend had been properly closed and put in order.

It was about six o’clock in the evening when I arrived, and there were many friends and relatives tenderly watering the flowers on the graves of their loved ones. Without much difficulty I found the newly made mound of brown earth, but to my surprise I also saw that a magnificent cross of white flowers had been laid upon it.
