The Secrets Of Rochester Place

Spring 1937: Teresa, a young Basque girl, is evacuated to London in the wake of the Guernica bombing. She thinks she has reached safety in the lofty halls of Rochester Place and the soothing arms of Mary Davidson, but trouble seeks her out wherever she goes...
Autumn 2020: Corrine, an emergency services operator, receives a call from a distressed woman called Mary. But when the ambulance arrives at Rochester Place - the address the woman gave them - she is nowhere to be found. No matter how hard she tries to forget, memories of Mary's raw fear haunt Corinne and secrets, long-hidden in Corinne's family tree, begin to surface.
Is Mary calling from beyond the grave? And what actually happened at Rochester Place all those years ago?
