Fourth of July weekend turns deadly in Cherry Hills, Washington when Kat Harper and her police detective boyfriend hear a gunshot in the midst of the neighborhood fireworks. A killer with a grudge has taken advantage of the small-town festivities to shoot a local divorce lawyer in cold blood. But who committed the murder: a disgruntled divorcé, the lawyer's own unloving wife, or someone else with homicidal tendencies? Kat doesn't know, but the amateur sleuth won't stop investigating until she figures out "whodunit" and the guilty party is celebrating their next holiday behind bars.
