'It gripped me for a week. Incredible!' JANICE HALLETT, author of THE TWYFORD CODE An endlessly inventive murder mystery' ALEX PAVESI, author of EIGHT DETECTIVES 'Mind-bendingly brilliant. Agatha Christie on steroids!' TIM GLISTER, author of RED CORONA A LOCKED ROOM. A BRUTAL MURDER. AND A KILLER WHO CAN UNWIND TIME... In the former mining town of Black Lake, there is an old story about a shipwreck with only one survivor. His descendants have a unique ability: once in their lives - and only once - they can unwind the events of the previous six hours. More than two hundred years later, part-time police constable Ella Manning is attending a party at Black Lake Manor, the cliff-top mansion belonging to the local billionaire. When a raging storm sweeps in from the Pacific, she and several other guests find themselves trapped. And when their host is discovered brutally murdered in his study the next morning, the door locked from the inside, they turn to her to solve the crime. Pushing her detective skills to the limit, against the odds Ella is sure she has identified the killer... but then someone undoes time. With no memory of what she discovered before, her investigation begins again, with very different results. Which of her suspects is guilty? And is there something even more sinister she is yet to uncover? Can she solve the mystery before time runs out... again? A must-read for fans of The Seven Deaths of Evelyn Hardcastle, The Sanatorium and And Then There Were None, Black Lake Manor will keep you feverishly turning the pages all night long!
