Later, Evanna helped me stop his nightmares. But the witch said it was only a temporary solution. When the dreams resumed, Harkat would have to find out the truth about himself or be driven insane.

For the last month Harkat had been tormented every time he slept. He stayed awake as long as he could Little People didn't need much sleep but whenever he dozed off, the nightmares washed over him and he'd thrash and scream in his sleep. It had reached the stage where he had to be tied down when he slept otherwise he stumbled through the camp, hitting out at imaginary monsters, causing damage to anything he encountered.

After five days and nights, he'd fallen asleep at the end of our latest show. I'd tied him down in his hammock, using strong ropes to strap his arms by his sides, and sat beside him while he tossed and moaned, wiping green beads of sweat from his forehead, away from his lidless eyes.

Finally, early in the morning, after hours of shrieking and straining, the cries stopped, his eyes cleared and he smiled weakly. "You can untie me … now. All done for tonight."

"That was a long one," I muttered, undoing the knots.

"That's the trouble with putting … sleep off so long," Harkat sighed, swinging out of his hammock. "I postpone the nightmares for a while, but I … sleep longer."

"Maybe you should try hypnosis again," I suggested. We'd done everything we could think of to ease Harkat's pain, asking all the performers and crew in the Cirque if they knew of a cure for nightmares. Mr Tall had tried hypnotizing him, Truska had sung to him while he slept, Rhamus Twobellies had rubbed a foul-smelling ointment over his head all to no avail.
