Fans of Catriona Ward and Stephen King will find plenty to enjoy in this biting horror novel where not all is what you see... or hear.

In 1983, experimental artist Tony Mathias began work on a new installation – it was to be a collage of visuals and sounds collected at an abandoned RAF base called Warden Fell. Various stories and rumours swirled around the place but Tony was interested only in the echoes of history. But soon after visiting the site to tape-record the sounds there, he returned to the caravan where he was staying with his family and killed his wife, his two children and then himself. Another dark twist in Warden Fell’s history?

But the past reaches out. Decades later Cally Darker, gets the chance to investigate the terrible story and perhaps even solve the mystery – a fantastic exclusive story for her true-crime podcast.Tony's actress sister Stella is desperate for the mystery to be solved before she dies will do all she can to help and passes on the tapes left behind by her brother. But before long, Cally realises that Warden Fell has a far older and darker story to tell. Be careful what you listen to…
