Evil remembers…

Falkenberg, Sweden.

Are the two murders the work of a serial killer, and how are they connected to shocking events at Buchenwald?

Emily Roy, a profiler on loan to Scotland Yard from the Canadian Royal Mounted Police, joins up with Linnea's friend, French true-crime writer Alexis Castells, to investigate the puzzling case. They travel between Sweden and London, and then deep into the past, as a startling and terrifying connection comes to light.


‘A terrific, original duo’ The Times

‘Multi-layered, superbly plotted, brimming with mystery, tension and bone-chilling violence, and with two very different – but equally fascinating – lead female characters, Block 46 is not for the squeamish or faint-hearted … this is a book that has the power to shock and the artistry to impress long after the last page has turned’ Lancashire Post

‘Utterly compelling’ Woman’s Own

‘A bold and audacious debut from a very talented writer. Heralds the beginning of a thrilling new series’ R J Ellory

‘Viscerally brutal yet delicately beautiful, like blood spatter on fresh snow. An unbelievable debut’ Matt Wesolowski
