The Haunting of Netherfield (гет)

It is a truth universally acknowledged that a deranged house in possession of spirits must be in want of a life. When the ghostly inhabitants of Netherfield set their sights on Jane, will Elizabeth's mind be strong enough to withstand the house's onslaught and save her sister? Crossover with the 1969 movie version of "The Haunting." HEA for E/D and J/B; everyone else is fair game.
