The Hellenic Police’s Alexandros Savva seeks the mastermind behind an attack that has left dozens dead and injured in Lesvos’ Sappho Square in this next installment of the series.

During the inquiry into Meda Tocci’s death, a map is taken off a murder suspect but it’s Savva’s wife who grasps its significance. But before he can convince his superiors of the evidence’s veracity, the worst happens. An offshoot of the National Revival of Greece blocks off Sappho Square and fires on the assembled crowd.

After failing to stop the attack, Savva and Colonel Petros Callas of the Athens Anti-Terror Unit scramble to capture a suspect seen walking away from his rifle and the slaughter without having fired a shot. Who was this man who abandoned his comrades? Every time Savva gets close, leads dry up, and he’s forced to concede that the mastermind of the attack is still at large and still very much a threat. With friends and officers dead and severely injured, Savva’s last hope is the blackmarket sale of a stolen, forged painting.

Meticulously tracing NRG’s member’s lives, Savva’s search takes him to Athens and back, and tantalizingly close to Anthony Goldstein. For terrorists aren’t the only ones that are stalking Lesvos in the night.
