The Will to Kill (Mike Hammer)

Someone in the wealthy Dunbar family has blood on their hands—and only hard-as-nails Mike Hammer has the skills to unmask them—in this page-turner for fans of gritty crime fiction
 
Taking a midnight stroll along the Hudson River, Mike Hammer gets more than he bargained for: a partial corpse on an ice floe. The body is that of a butler who spent the last years of his life working for a millionaire—also now deceased—and his notoriously privileged children.

Were both master and servant murdered? Captain Pat Chambers thinks so. But to prove it, Hammer must travel to upstate New York to investigate the dead man’s family, all of whom have a motive for murder—and one of whom who has a taste for it.
