The Interval

Every forty-eight hours, someone dies. No visible wounds. No obvious cause. No apparent connection. When environmental systems researcher Mia Scholz is found dead at her desk in Berlin, there is nothing to explain what happened. Two nights later, journalist Thomas Reimer is discovered dead in his car, his final message left unfinished. The timing is impossible to ignore. Detective Sarah Hallow is brought in to help Berlin police determine whether the deaths are connected. As another victim falls and the forty-eight-hour interval begins to look like a schedule, the investigation races to identify who might be next. But Sarah has learned to distrust patterns that become answers too quickly. The victims are connected by something deeper than time: a chain of reports, permissions, infrastructure systems and decisions stretching across the city. And every move the police make changes the system they are trying to understand. Soon, the killer is no longer simply following a pattern. He is watching what the investigation does with it. As police protection tightens, a journalist closes in on a buried institutional failure, and the predicted hour approaches again, Sarah must answer a more dangerous question: Can you stop the next death when the act of predicting it may be exactly what the killer needs? The Interval is a tense psychological crime thriller about certainty, systems and the danger of finding the right answer too soon. The second novel in the Sarah Hallow Investigations series.
