“A,” Desdemona said as the planchette stopped moving. “That’s not
demon. It has too many letters. Did you get all of it?”
Thin Man nodded slowly.
“Well?” she demanded. “What does it say.”
He showed her the pad of paper again.
In blocky letters, the page read: DESDEMONA.
She squinted at it, and then the Ouija board, and then back at the pad of
paper as Thin Man turned and pointed the word toward the camera. “That’s
my name.” The blood drained from her face as she pulled her hands away
from the planchette. “Are you … are you saying that I murdered you?” She
laughed uncomfortably. “That’s impossible. I’ve never murdered anyone
before.”
Thin Man and Desdemona froze as the planchette began to move without
her touching it. She rattled off the letters Wallace paused upon, and Thin Man
wrote them down.
“You totally killed me,” Desdemona read off the paper before blinking.
“What? I did not. Who are you? Is this some kind of joke?” She bent over the
underside of the table before sitting back up. “No magnets. Hugo. Hugo. Are
you doing this? I don’t like to be tricked.”
“You’re messing with forces you can’t even begin to comprehend,” Hugo
said solemnly.
The planchette moved again.
“Ha, ha,” Thin Man read aloud as he wrote the letters down. “You suck.”
“What are you, ten?” Nelson asked, though he seemed to be fighting a
smile. “You need to be scarier. Tell her you’re Satan, and you’re going to eat
her liver.”
“This is Satan,” Thin Man said as the planchette moved. “I’m going to eat
your diver.”
“Liver,” Nelson said. “Liver.”
“I’m trying,” Wallace said through gritted teeth. “It’s slippery!”
“My diver?” Desdemona asked, sounding confused. “I’ve never been
diving in my life.”
The planchette moved again. “Sorry,” Thin Man read as he wrote down
the new message. “Stupid autocorrect. I meant liver.”
Hugo put his face in his hands and groaned.
