When Kent Abner — baby doctor, model husband and father, good neighbour — is found dead in his town house in the West Village, Detective Eve Dallas and her team have a real mystery on their hands. Who would want to kill such a good man? They know how, where and when he was killed but why did someone want him dead?

Then a second victim is discovered and as Spring arrives in New York City, Eve finds herself in a race against time to track down a serial killer with a motive she can't fathom and a weapon of choice which could wipe out half of Manhattan.
