'I have always gotten along better with plants than with people ...' Eustacia Rose is a professor of botany. Her specialty: plant toxicology. She lives alone in London - only her extensive collection of poisonous plants keeps her company. She cherishes and cares for them with meticulous care. Her life is quiet, her daily routine never changes. Until one day she hears a scream and the temptation to pursue it is irresistible. Through her telescope, Eustacia is drawn into the life of her extraordinarily beautiful neighbor Simone. But then Simone is kidnapped, and Eustacia finds herself in a far more complicated web than she could ever have imagined. For all fans of Mark Haddon and Richard Osman
