London cycle courier Astrid Bell is bad luck- for other people. First, Astrid's neighbour Peggy Farrell accidentally knocks her off her bike- and not long after is found bludgeoned to death in an alley. Then, a few days later, Astrid is asked to pick up a package- only to find the client slashed to pieces in the hallway.
For the police, it's more than a mere coincidence. For Astrid and her six housemates, it's the beginning of a nightmare: suspicious glances, bitter accusations, fallings out and a growing fear that the worst is yet to come.

I felt as though the characters and the dialogue really let this book down as neither were believable. Even when Astrid and her housemates were talking to the police, I failed to find it realistic in any way.
I wouldn't let this review put you off Nicci French's other books, I have read Catch Me When I Fall, The Red Room and Secret Smile, all of which were excellent but Until It's Over just didn't do it for me.
