A Greek American tourist, Lydia Pappas, stumbles upon a child's body in the ruins of an ancient temple, well hidden on the top of a cliff. The boy has been bled dry, though no blood is in evidence, leading the Greek police investigator, Yiannis Patronas, to believe the killer must have collected it. Greece's financial crisis has reduced the police force on Sifnos to one officer, Petros Nikolaidis, so Patronas has been summoned from his home base of Chios to aid in the case. Accompanying him are his colleagues, Giorgos Tembelos and Evangelos Demos, as well as Papa Michalis, an ancient Orthodox priest with a vast knowledge of detective fiction and an uncanny ability to ferret out the truth. Though eccentric and often irritating, Michalis has been an asset to Patronas over the years in a land where homicide was, until recently, a rare occurrence. But Greece is changing daily, with a tide of migrants straining the country's already diminished resources and occasionally bringing out the worst in her people. The child appears to have been sacrificed according to the rules of a pagan religious ritual. Is someone on Sifnos reviving the old ways? Or is there a thrill killer loose on the island? Is the culprit a Greek national or one of the many foreign migrants crowding its refugee camps? Book 3 in the Greek Islands Mystery series.
