“Plunge thy knife into my breast, Sir King,” she said, “and with my last sigh I will praise thee.”

“What!” he snarled—“so much in love with Death? We’ll see to it thy desire’s whetted in his fondling. He shall prick thee here and there before ye close. Away with her to the Watch Tower!”

It was at least a respite, and she had dreaded the instant worst. This Watch, or Round Turret, rose from the north-east angle of the great Keep. He had her there at his mercy. Her cries might rise to heaven, but could not penetrate the dense fabric below. In this chill, high dungeon they imprisoned the girl. Its cold, its dreadful loneliness, scant food, and the silent guard should break her spirit, the wretch thought. He would taste her submission to the dregs, then fling her to his lackeys to teach her what it meant to flout her King. She answered by starving herself; on which came Kay, the silky-tongued, and warned her smoothly that such contumacy could only invite its swift reprisal. She would not be permitted so to slip through her royal lover’s hands. Whereat she ate all that they would give her, and despaired the more.

There was no escape, none. Locked in as she was, she knew that her every movement was canvassed by hidden eyes, her every sigh recorded. And Robin made no sign.

One day it moved her to hear unwonted sounds rising from the outer ward below, into which the public were admitted on occasion of State festivities, executions, and so forth. The multitudinous jollity of voices, soaring above the whine of bugle and tap of drum, proclaimed it a May-day revel, when the whole place was delivered over to sport and merriment.

She could not see from her high, narrow window, sunk deep in the wall; but the babble flowing in on a shaft of sunlight made her heart warm as it had never felt for days. Some spirit of release seemed to ride in on the happy music, some emotion that made her bosom heave and her eyes fill thick with tears.

She was standing, drinking in the merry noise, when her lids blinked involuntarily, and, with a swish and smack on the ceiling of her cell, something alighted at her feet. She fancied on the instant that a bird had flown in and struck against the stone; but, looking down quickly, she saw that it was a broken arrow—one of a dear, familiar pattern. With a gasp she stooped, snatched at it, and stood listening. There was no sign of anyone having observed. With swift trembling fingers she detached a strand of green worsted which was knotted about the shaft under the quill, and found beneath a folded scrap of parchment, which, on being opened, revealed a glutinous smear of brown substance, and just these four woeful words written above:

Poor Robin’s Pledge. Farewell.

It was her death-warrant.

So sweet and tragic, her heart near stopped from its sorrow as she read it. She knew at once what it was—a mortal Arab poison, given long years ago to her woodland lover by a follower of the Lion King. It might serve him in a sore need, had been the words accompanying the gift—to taste it was death. And once Robin had shown it to her, proposing, half playfully, that they should pledge one another in its Lethe were Fate ever to dispart them.
