The Least of Men

Sixteen years ago, Chicago surgeon Dr. David Carroll lost everything.

When Russian mafia boss Dimitri Barkov tried to seize Carroll’s medical practice, David refused. Barkov’s retaliation was swift and brutal—David’s wife murdered, federal agents gunned down, and David forced into hiding in the remote wilderness of Scotland’s Outer Hebrides. The world believed the story ended there, with David dead and the Barkov empire untouched.

They were wrong.

Now, in 2021, a far more disturbing criminal enterprise is flourishing—an international network trafficking young girls to wealthy clients who are willing to pay anything to satisfy their darkest desires. At its center stands Amy Arnold, a ruthless mastermind who has built her empire on violence, secrecy, and the belief that no one can stop her.
But buried in the past is a man who has already lost everything—and men like that are the most dangerous of all.

As investigators, criminals, and survivors collide across continents, old crimes resurface and long-hidden truths emerge. In a world where power protects the guilty and innocence is a rare commodity, justice may depend on the least likely champions.
And the least of men may prove to be the most relentless.
