Arbella Stuart (if indeed that was her) isn't the only angry ghost in the Tower of London.
Over in the White Tower, there is another, which seems intent upon removing intruders at any cost.
The White Tower was the first building built by the Norman conquerors on Tower Hill. It still contains many of the greatest treasures of England, including the Crown Jewels.
If we believe the English (we don't), the animated and sentient head of Bran the Blessed is hidden here somewhere. It was taken from Harlech in order to prevent the Welsh God protecting the coastline there.
Amongst some of the more tangible of the priceless items on show in the White Tower is the armor of Henry VIII. It is exhibited, in all its over-sized and manly exaggeration, in a long room named The Gallery. And this is where a sentry ghost attacks visitors at night.
Of course, the only people entering the place after dark are the Beefeaters. It is part of their patrol duties to ensure that all is secure. Therefore, all of these stories come from them.
One night, a Yeomen Guard careered in through the guardroom doorway. He was obviously traumatized. His neck was raw with welts and ripening bruises. He looked like he'd been hanged.
His colleagues were naturally a bit perturbed. They questioned him; and eventually, after he'd got his breath, the story was gushed out.
He had been in the Gallery, walking alongside the Henry VIII armor exhibition, when it felt like a heavy cape was draped over him from behind. He struggled under it, plainly able to see that there was nothing there.
The evidence of his eyes was surely lacking, because the cape's cord was being pulled tightly around his neck. Eyes bulging and unable to breathe, the Beefeater tried to fight his invisible assailant.
Then common sense (if such a thing can apply to this situation) kicked in. He staggered towards the exit, carrying his weight and in fear of losing consciousness. Stars filled his vision. He used the last of his strength to get to the door and stepped out.
It was over. It always is. When the Gallery ghost attacks, it can be with blows or thumps or any other physical means, but it's always over at the threshold. The phantom only wants them to leave.
