The first attempt at killing her husband was the night of the dinner party. After forty years, Thom Graves has become a disappointment to his wife, Wendy - he drinks too much, flirts with other women, and worst of all, is in danger of revealing their darkest secrets. Reasoning that her life will be better without him, Wendy's starting to think the only way to bury the truth is to bury her husband with it - all she has to do is get away with it.
Starting at the end, and ending at the beginning, Kill Your Darlings is an ingenious drip-feed mystery about two people's life together and the secrets which fatally bind them.
