Ones at a time

SYNOPSIS: Something's happening to my late granmother's mansion. It's been three months since i inherited it, and most of the people I've sent to inspect the place.. haven't come back. The few who did say the mansion is cursed. They spoke of whispers and shadows that move when no one's there. I was told you're the only one capable of handling this. You're my last hope. I'll pay you, just bring me answers. And... be careful.
