«Every Day is Mother's Day» by Hilary Mantel

Evelyn and Muriel Axon, mother and daughter, lead a haunted existence. Objects of horror to their neighbours, they evade or terrorise any social worker who crosses their path. Inside their house, they pursue a covert persecution of each other, shrinking from the unseen occupants of their spare room. But change is in the air… Every Day is Mother's Day is a merciless comedy of colliding lives: of sex, death, madness, adultery and the social services.
