A serial killer to chill your bones. A psychopath more frightening than Hannibal Lecter. Set in London's Blackheath, Rattle is the number one bestselling psychological thriller from the author of When I Was Ten, Fiona Cummins.

'Harrowing and horrifying' - Val McDermid, author of the Tony Hill and Carol Jordan series

He has planned well. He leads two lives. In one, he's just like anyone else. But, in the other, he is the caretaker of his family's grotesque, terrifying museum.

Now, the time has come to add to his collection.

Jakey Frith and Clara Foyle have something in common. They have what he needs.

And so begins a terrifying game of cat-and-mouse between the sinister collector, Jakey's father and Etta Fitzroy - a troubled detective investigating a spate of abductions.

Because he is ready to feed his obsession.

And he is on the hunt.

Rattle by Fiona Cummins explores the seam of darkness that runs through us all; the struggle between light and shadow, redemption and revenge. It is a glimpse into the mind of a sinister psychopath. And it is also a story about not giving up hope - even when it seems that all hope is already lost.
