Apartment 16 - Adam L. G Nevill

In Barrington House in London, there is an empty apartment.
No one goes in, no one comes out.
And it's been that way for fifty years.
Until the night watchman hears a disturbance after midnight and investigates.
What he experiences changes his life forever.
A young American woman, Apryl, arrives at Barrington House.
She's been left an apartment by her Great Aunt Lillian who died in strange circumstances.
Rumours claim Lillian was mad.
But her diary suggests she was implicated in a horrific and inexplicable event decades ago.
Determined to learn something of her aunt and Barrington House, Apryl discovers that a transforming evil still inhabits the building.
And the doorway to Apartment 16 is a gateway to something altogether more terrifying...
