When the artists scattered in the autumn and he returned to Edinburgh and Mrs. Osbourne to California, he carried with him the hope that some time in the future they should be married.
For the next three years he worked hard. He published numerous essays in the Cornhill Magazine and his first short stories, "A Lodging for the Night," "Will O' the Mill," and the "New Arabian Nights." These were followed by his first books of travel, "An Inland Voyage," giving a faithful account of the adventures of the Arethusa and the Cigarette, and "Travels with a Donkey in the Cévennes."
When the latter was published, Mr. Walter Crane made an illustration for it showing R.L.S. under a tree in the foreground in his sleeping-bag, smoking, while Modestine contentedly crops grass by his side. Above him winds the path he is to take on his journey, encouraging Modestine with her burden to a livelier pace with his goad; receiving the blessing of the good monks at the Monastery of Our Lady of the Snows; stopping for a bite and sup at a wayside tavern; conversing with a fellow traveller by the way; and finally disappearing with the sunset over the brow of the hill.
Some time previous to all this he had written in a letter: "Leslie Stephen, who was down here to lecture, called on me, and took me up to see a poor fellow, a poet who writes for him, and who has been eighteen months in our Infirmary, and may be for all I know eighteen months more. Stephen and I sat on a couple of chairs, and the poor fellow sat up in his bed with his hair and beard all tangled, and talked as cheerfully as if he had been in a king's palace of blue air."
This was William Ernest Henley, and his brave determination to live and work, though he knew he must ever remain in a maimed condition, roused Stevenson's sincere admiration. With his usual impetuous generosity, he brought him books and other comforts to make his prolonged stay in the infirmary less wearisome and a warm friendship sprang up between them.
As Henley grew stronger they planned to work together and write plays. Stevenson had done nothing of the kind since he was nineteen. Now they chose to use the same plot that he had experimented with at that time. It was the story of the notorious Deacon Brodie of Edinburgh, which both considered contained good material for a play.
"A great man in his day was the Deacon; well seen in good society, crafty with his hands as a cabinet-maker, and one who could sing a song with taste. Many a citizen was proud to welcome the Deacon to supper, and dismiss him with regret ... who would have been vastly disconcerted had he known how soon, and in what guise his visitor returned. Many stories are told of this redoubtable Edinburgh burgher.... A friend of Brodie's ... told him of a projected visit to the country, and afterwards detained by some affairs, put it off and stayed the night in town. The good man had lain some time awake; it was far on in the small hours by the Tron bell; when suddenly there came a crack, a jar, a faint light. Softly he clambered out of bed and up to a false window which looked upon another room, and there, by the glimmer of a thieves' lantern, was his good friend the Deacon in a mask."
At length after a certain robbery in one of the government offices the Deacon was suspected. He escaped to Holland, but was arrested in Amsterdam as he was about to start for America. He was brought back to Edinburgh, was tried and convicted and hanged on the second of October, 1788, at the west end of the Tolbooth, which was the famous old Edinburgh prison known as the Heart of Midlothian.
