The unheard / Nicci French.

First published in 2021.

'He did kill. Kill and kill and kill.' Tess's number one priority has always been her three-year-old daughter Poppy. But splitting up with Poppy's father Jason means that she cannot always be there to keep her daughter safe. When she finds a disturbing drawing, dark and menacing, among her daughter's brightly coloured paintings, Tess is convinced that Poppy has witnessed something terrible. Something that her young mind is struggling to put into words. But no one will listen. It's only a child's drawing, isn't it? Tess will protect Poppy, whatever the price. But when she doesn't know what, or who, she is protecting her from, how can she possibly know who to trust . . . ?
