The Bloody Cupcake

Joe tried to scream again, but his mouth was gagged, and he’d lost a lot of blood.
Luke.
That bastard.
He knew!
How? Who told him?
Luke wiped the blood from his knife. “Hey, I can check one thing off my resolution list.”
Eyes stinging from gasoline dripping from his hair, Joe stared at the cupcake, topped with a sickly sheen of blood.
His blood.
“Oh, right,” said Luke. “The candle. Silly me.”
Luke took out a candle and stuck it in the cupcake.
And lit it.
“Make a wish,” said Luke, and he flicked the lit candle at Joe.
