What would you do if someone was trying to kill you, but you couldn't go to the police because that would mean revealing a secret that might destroy your family, the very same secret that might be about to get you killed? That is Sally Thorning's predicament in 'The Point of Rescue' - a superb thriller that is flawlessly written, deeply intelligent, pacy, gripping and totally unpredictable. In some ways this is a traditional detective story, for there are police characters working on unravelling the various mysteries and the irresistible sense of a puzzle needing to be solved is paramount, but this is also a hunted-woman thriller, also a very sophisticated pyschological suspense novel, and a book about relationships and a woman's role in society. I read oodles of thrillers, and it's very rare to find any that pay as much attention to depth and layers and psychology (proper characterisation, I suppose I mean)as to the logic-puzzle-style plot. This is not a 'locked-room' mystery, as there's no locked room, but it has that same sense of things which seem impossible but we know they can't be, because they've happened...how will it be resolved? Sophie Hannah pulls several twists out of the bag and the end, and a few moments of blood-curdling horror as the reader becomes aware of the depths of suffering involved. Loved it!
