Although so long a time has elapsed since the grim tragedy I am about to record, I cannot think of it even now without a shudder. The story of the life of every man and woman is probably more or less a tragedy, but nothing I have ever heard of can compare in ghastly, weird horror with all the peculiar circumstances of the case in point. Most certainly I would never have put pen to paper to record it had it not been from a sense of duty. Long years ago certain garbled versions crept into the public journals, and though at the time I did not consider it desirable to contradict them, I do think now that the moment has come when I, the only living being fully acquainted with the facts, should make them known, otherwise lies will become history, and posterity will accept it as truth. But there is still another reason I may venture to advance for breaking the silence of years. I think in the interest of science the case should be recorded. I have not always held this view, but when a man bends under the weight of years, and he sniffs the mould of his grave, his ideas undergo a complete change, and the opinions of his youth are not the opinions of his old age. There may be exceptions to this, but I fancy they must be very few. With these preliminary remarks I will plunge at once into my story. It was the end of August 1857 that I acted as best man at the wedding of my friend Jack Redcar, C.E. It was a memorable year, for our hold on our magnificent Indian Empire had nearly been shaken loose by a mutiny which had threatened to spread throughout the whole of India. At the beginning of 1856 I had returned home from India after a three years’ spell. I had gone out as a young medico in the service of the H.E.I.C., but my health broke down and I was compelled to resign my appointment. A year later my friend Redcar, who had also been in the Company’s service as a civil engineer, came back to England, as his father had recently died and left him a modest fortune. Jack was not only my senior in years, but I had always considered him my superior in every respect. We were at a public school together, and both went up to Oxford, though not together, for he was finishing his final year when I was a freshman.
