My Grandmother's Daughter

Based on real events this story is taken from the life of my great grandparents. After their eccentric grandmother's untimely death five siblings are forced to fly back to Pakistan to attend her funeral, leading them to spend a few weeks in her rotten ancient eldritch manor along with an aunt they didn't know they had. Things take sinister turns however when the giant oak tree inside the house has their grandmother's corpse hanging from it one fine morning and there are dead crows attached to the ceiling.
