And Come Day's End

Implicated in his best friend Lenny's death, Michael McKaybees finds himself entangled in a web woven by someone who wants him destroyed. And then Michael's father, Private Investigator Marlowe Black, shows up-after an absence of more than three decades. It turns out he, too, is a suspect in Lenny's death.
And Come Day's End: A Michael McKaybees Mystery reunites two men who were estranged by choice and now must attempt together to avoid life in prison for a murder neither committed. From gambling and money laundering to revenge and murder, And Come Day's End offers thrilling twenty-first-century stakes, but author Gabriel F.W. Koch spends as much time on father/son conflict as he does the darkest of noir, twisting the plot into a series of choices that can lead to a lawful conclusion-or to McKaybees and Black themselves crossing into criminality.
And Come Day's End is the 2019 Best Mystery winner of the Hollywood Book Awards contest.
