Moving from a London deep in the terror of the Blitz to the seemingly safer London of 2019, two women have to fight for their lives to survive a ruthless killer in this dual timeline psychological thriller that will make your hair stand on end!

London, 1941. Amongst the air-raid sirens and horrors of bombings, artist Harriet Yorke manages Calla House: a small community of people from different backgrounds - but good friends who pull together in times of crisis.

Like most Londoners contending with the Blitz, Harriet has grown used to withstanding danger, but when she goes on a late-evening stroll with her Cairn Terrier, George, and finds herself face to face with a killer, she unleashes a series of events that will put more than just her own life on the line . . .

London, 2019. Libby lives amongst her grandmother's paintings in Calla House - works of art into which Harriet poured all the horror of her wartime experiences, culminating in that one terrifying night.

Libby's Calla House is a comfortable safe haven for her and its other residents - until, that is, a crumbling chimney pot sparks an alert. Libby calls in builders, but as her troubles magnify, she begins to wonder if the ghosts of Harriet's past aren't going to bring more than the house down around her ears . . .

Fans of Charlie Donlea's The Girl Who Was Taken and Riley Sager's The Only One Left will thoroughly enjoy this unputdownable creepy and suspenseful novel, filled with unexpected twists and turns and keeps the reader guessing until the very end!
