Without Mercy

Detective Superintendent Hannah Bernstein of Special Branch is mending in a hospital bed when a figure out of her past slips into the room. Driven by a long-nursed hatred, the intruder completes what an earlier attack began, and Hannah does not survive.

Her death hits Sean Dillon, Blake Johnson and everyone close to her hard. Grief turns quickly to fury, and they pledge to hunt down those responsible, whatever the cost and wherever the trail leads.

None of them can foresee how punishing that pursuit will become, or how deep into a violent conflict it will pull them. This is a Sean Dillon thriller, a tense tale of revenge and international intrigue in which the people at its center are shaped as much by loyalty and loss as by the fight itself.
