Knock Knock

Whatever you do, don’t open the door…

When a severed foot is delivered to the unsuspecting residents of a student house in Norwich, DCI Kett’s Extreme Crime Task Force begins one of the most gruesome investigations of its career.

It’s not just a foot. More packages begin to appear at random on people’s doorsteps, all of them containing body parts that have been surgically removed and meticulously wrapped.

Kett, Porter, Savage and PC Duke find themselves in a race against the clock to identify the victims and their killer, who shows no sign of stopping.

And it soon becomes clear that this monster isn’t just delivering corpses.

He's sending a message.

Alex Smith books, the DCI Robert Kett and DI Harrison Baird thrillers, have monsters in them too, although these monsters are very human, and all the more terrifying for it. In between, he has published fourteen novels for children and teenagers under his full name, Alexander Gordon Smith—including the number one bestselling series Escape From Furnace. He lives in Norwich with his wife and three young daughters.

Tim Bruce is seasoned narrator having narrated over 200 audiobooks. This includes both fiction and non-fiction and most notably Lynda La Plante’s Framed and Albert Roux’s My Life in Food. When he is not narrating he is acting and has been in many TV soaps and in the West End production of Blood Brothers.???????
