It's a beautiful Spring day in NYC when Lt. Eve Dallas gets an early morning murder call. A talented young sculptor hasn't had such a perfect day in May. Killed by her own hammer, at first it looks like an argument with a jealous partner but it soon becomes clear that there is much more to this case than a lovers' quarrel turned fatal.   

Eve finds herself drawn into the dark and dangerous world of a secret order. A world in which white supremacy, misogyny and religious fanaticism are everyday activities. Eve has dealt with some tough cases before, but is it too much even for her to take on a wealthy, influential organisation with friends in very high places.....?
