"When was the last killing?"

"Monday." Sam flicked through the case file. "There's been a killing every three days for the last two weeks. All the blood was drained from their bodies; all found in the local high school football field."

Dean chewed his lip, thinking. "Connection between the vics?"

"Only that their bodies were all found in the same place and they all bled out from their Achilles heel. Otherwise, no connection at all."

"Okay. So if the pattern holds, there'll be another killing tonight." Dean grinned, rubbing his hands together. "Damn, I love a good old-fashioned monster hunt!"
