While my husband and Mr. Henley were engaged in writing plays in Bournemouth they made a number of titles, hoping to use them in the future. Dramatic composition was not what my husband preferred, but the torrent of Mr. Henley’s enthusiasm swept him off his feet. However, after several plays had been finished, and his health seriously impaired by his endeavours to keep up with Mr. Henley, play writing was abandoned forever, and my husband returned to his legitimate vocation. Having added one of the titles, The Hanging Judge, to the list of projected plays, now thrown aside, and emboldened by my husband’s offer to give me any help needed, I concluded to try and write it myself.

As I wanted a trial scene in the Old Bailey, I chose the period of 1700 for my purpose; but being shamefully ignorant of my subject, and my husband confessing to little more knowledge than I possessed, a London bookseller was commissioned to send us everything he could procure bearing on Old Bailey trials. A great package came in response to our order, and very soon we were both absorbed, not so much in the trials as in following the brilliant career of a Mr. Garrow, who appeared as counsel in many of the cases. We sent for more books, and yet more, still intent on Mr. Garrow, whose subtle cross–examination of witnesses and masterly, if if sometimes startling, methods of arriving at the truth seemed more thrilling to us than any novel.

Occasionally other trials than those of the Old Bailey would be included in the package of books we received from London; among these my husband found and read with avidity:—

My husband was always interested in this period of his country’s history, and had already the intention of writing a story that should turn on the Appin murder. The tale was to be of a boy, David Balfour, supposed to belong to my husband’s own family, who should travel in Scotland as though it were a foreign country, meeting with various adventures and misadventures by the way. From the trial of James Stewart my husband gleaned much valuable material for his novel, the most important being the character of Alan Breck. Aside from having described him as “smallish in stature,” my husband seems to have taken Alan Breck’s personal appearance, even to his clothing, from the book.

A letter from James Stewart to Mr. John Macfarlane, introduced as evidence in the trial, says: “There is one Alan Stewart, a distant friend of the late Ardshiel’s, who is in the French service, and came over in March last, as he said to some, in order to settle at home; to others, that he was to go soon back; and was, as I hear, the day that the murder was committed, seen not far from the place where it happened, and is not now to be seen; by which it is believed he was the actor. He is a desperate foolish fellow; and if he is guilty, came to the country for that very purpose. He is a tall, pock–pitted lad, very black hair, and wore a blue coat and metal buttons, an old red vest, and breeches of the same colour.” A second witness testified to having seen him wearing “a blue coat with silver buttons, a red waistcoat, black shag breeches, tartan hose, and a feathered hat, with a big coat, dun coloured,” a costume referred to by one of the counsel as “French cloathes which were remarkable.”

‘It was this restlessness, this insecurity, perhaps, that drove me further and further afield in my exploring expeditions. Going to the south-westward towards the rising country that is now called Combe Wood, I observed far off, in the direction of nineteenth-century Banstead, a vast green structure, different in character from any I had hitherto seen. It was larger than the largest of the palaces or ruins I knew, and the facade had an Oriental look: the face of it having the lustre, as well as the pale-green tint, a kind of bluish-green, of a certain type of Chinese porcelain. This difference in aspect suggested a difference in use, and I was minded to push on and explore. But the day was growing late, and I had come upon the sight of the place after a long and tiring circuit; so I resolved to hold over the adventure for the following day, and I returned to the welcome and the caresses of little Weena. But next morning I perceived clearly enough that my curiosity regarding the Palace of Green Porcelain was a piece of self-deception, to enable me to shirk, by another day, an experience I dreaded. I resolved I would make the descent without further waste of time, and started out in the early morning towards a well near the ruins of granite and aluminium.

‘Little Weena ran with me. She danced beside me to the well, but when she saw me lean over the mouth and look downward, she seemed strangely disconcerted. “Good-bye, Little Weena,” I said, kissing her; and then putting her down, I began to feel over the parapet for the climbing hooks. Rather hastily, I may as well confess, for I feared my courage might leak away! At first she watched me in amazement. Then she gave a most piteous cry, and running to me, she began to pull at me with her little hands. I think her opposition nerved me rather to proceed. I shook her off, perhaps a little roughly, and in another moment I was in the throat of the well. I saw her agonized face over the parapet, and smiled to reassure her. Then I had to look down at the unstable hooks to which I clung.

‘I had to clamber down a shaft of perhaps two hundred yards. The descent was effected by means of metallic bars projecting from the sides of the well, and these being adapted to the needs of a creature much smaller and lighter than myself, I was speedily cramped and fatigued by the descent. And not simply fatigued! One of the bars bent suddenly under my weight, and almost swung me off into the blackness beneath. For a moment I hung by one hand, and after that experience I did not dare to rest again. Though my arms and back were presently acutely painful, I went on clambering down the sheer descent with as quick a motion as possible. Glancing upward, I saw the aperture, a small blue disk, in which a star was visible, while little Weena’s head showed as a round black projection. The thudding sound of a machine below grew louder and more oppressive. Everything save that little disk above was profoundly dark, and when I looked up again Weena had disappeared.
