Make a Home of Me by Vanessa Santos

Peer through the keyhole and you'll see a mysterious dinner party with a sickening twist; a woman's intense new relationship with a single father and his strangely shy daughter; the rediscovered journals of a famous artist with a singular obsession who disappeared in suspicious circumstances; a family driven to desperation by the impossible appearance of nonsensical notes; and a seemingly happily married couple driven to the edge of despair by a neighbour's crying baby.
