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.

And is there something even more sinister she is yet to uncover? Can she solve the mystery before time runs out... again?
