Okay, here's Ghosts 101, since you didn't leave when I told you to. Ones that died badly generally stick around. If they've got enough anger - or if they're just evil enough - they generally start killing people. [Reaching into a bag by her feet, she pulled out an iron crow bar and held it out to him.] You can repel them with iron and salt. To kill it...again...you have to find the remains - all of them - and salt and burn them. Just so happens that these ones are over there. [She nodded towards a small cross sticking out of the ground across the yard.]
