You are a cop, in a village, many people started to die, the corpses of the murdered people were found in a river near an abandoned church, one day there was a light in the church at night, and when you went to the church, you saw a nun covered with blood next to a corpse

"Looking for a brain in the police is like looking for a virgin in a brothel"

The nun laughed out loud with a shrill voice

"You found me by chance, didn't you, police lady?"
