What was it, who was it, that was writing in the bed?

Who can say?

Was it Gilbert Lothian, the young and kindly-natured man who reverenced all things that were pure, beautiful and of good report?

Or was it that dreadful other self, the Being created out of poison, that was laying sure and stealthy fingers upon the Soul, that "glorious Devil large of heart and brain"?

Who can tell?

The subtle knowledge of the great doctor could not have said, the holy love of the young matron could not have divined.

These things are hidden yet, and still will be.

The hump of the bed-clothes sank. The pad fell flat. The figure stretched out towards the table, there was the stealthy trickle of liquid, the gurgle of a body, drinking.

Then the bed-clothes rose once more, the pad went to its place, the figure stiffened; and the red pen moved obedient to that which controlled it, setting down the jewelled words upon the page.

—The first of the long series of letters that the Girl of the Library was destined to receive! Not the most beautiful perhaps, not the most wonderful. Passion was not born yet, and if love was, there was no concrete word of it here. No one but Gilbert Lothian ever knew what was born on that fated midnight, when he wrote this first subtle letter, deadly for this girl to receive, perhaps, from such a man, at such a time in her life.
