Mrs Murchisson blinked myopically. "I might have - Ah!" She stopped as the muzzle of a gun was thrust against her stomach.

"I said, 'trick or treat!'" her assailant growled.

"Trick," Mrs Murchisson replied.

Cal Bridgerman wavered. He had not expected this. "Lady - I'm here for a treat, and you're gonna give me whatever treat I want!"

"Oh no, young man. You misunderstand." A piercing light shone from the old lady's eyes, and a cold breeze sprung as if from nowhere. "When I said 'trick', I meant it."

Something unfurled from the night and lunged towards Cal.
