I don’t delay, as Elizabeth would delay. I don’t drag my feet and puzzle away and put myself to bed, pretending illness as she does whenever she is afraid. I see a chance when it comes to me and I take it like a woman of courage. “Yes,” I say to my rescuer. “Oui,” I say to the gods of fortune, to life itself.

And when he says to me, “When?” I say, “Tonight.”

I don’t fear, I am frightened of nothing. I escaped from my own palace at Holyrood when I was held by murderers; I escaped from Linlithgow Castle. They will see that they can take me but they cannot hold me. Bothwell himself said that to me once, he said, “A man can take you, but you cling to your belief that he can never own you.” And I replied, “I am always queen. No man can command me.”

The walls of Bolton Castle are rough-hewn gray stone, a place built to resist cannon, but I have a rope around my waist and thick gloves to protect my hands and stout boots so that I can kick myself away. The window is narrow, little more than a slit in the stone, but I am slim and lithe, and I can wriggle out and sit with my back to the very edge of the precipice, looking down. The porter takes the rope and hands it to Agnes Livingstone and watches her as she ties it around my waist. He makes a gesture to tell her to check that it is tight. He cannot touch me, my body is sacred, so she has to do everything under his instruction. I am watching his face. He is not an adherent of mine, but he has been paid well, and he looks determined to do his part in this. I think I can trust him. I give him a little smile and he sees my lip tremble with fear, for he says, in his rough northern accent, “Dinnae fret, pet.” And I smile as if I understand him and watch him wind the rope around his waist. He braces himself and I wriggle to the very brink and look down.

Dear God, I cannot see the ground. Below me is darkness and the howl of air. I cling to the post of the window as if I cannot let it go. Agnes is white with fear, the porter’s face steady. If I am going to go, I have to go now. I release the comfort of the stone arch of the window, I let myself stretch out onto the rope. I step out into air. I feel the rope go taut and terrifyingly thin, and I start to walk backwards, into the darkness, into nothingness, my feet pushing against the great stones of the walls, my skirt filling and flapping in the wind.
