"How would you deal with a demon-possessed corpse?" asked Harold. "Just for argument's sake. Blue sky thinking. Any method you can come up with."
Julie stirred her coffee, the tink tink tink a counterpoint to the low grumble of the dishwasher in the background.
"Devious? Shut up. It was your turn to do the pots so stop moaning about it."
"Yes sir." Devious ran extra hot water, scowling at the reflection of the back of Harold's head.
"Nuclear bomb?" Julie took a sip of coffee. "Engineer a tidal wave? Meteor strike? Napalm? Neutron bomb?"
Harold sucked air between his teeth. "A little more precise. Imagine there are people among them, hiding out."
"Is a demon possessed corpse a zombie?"
"More or less."
"Then the people are expendable. Fireball the lot."
"That's less blue sky and more air head." Harold stood an action figure on the table. "Let's make it just one demon-possessed zombie. You have to stop the meat but catch the demonic spirit inside it."
"What's that when it's at home?"
"A mirror inscribed with a portal to itself. Any spirit looking into it will be trapped inside."
"How long for?"
"Until the mirror is broken."
"Great! Can you make one of those?"
Julie shook her head. "Of course not. There's no such thing."
Harold let out a deep sigh. "Apart from a soul trap, what other method would you use?"
Julie put down her coffee and smiled. "A bottle of liquid nitrogen and a hammer."
