People across the city are dying under strange, unexplained circumstances. Each of them received a phone call within twenty-four hours of their death. No phone number. No trace. No voice. Only a few seconds of static from the other end of the line. One day later, they are dead. The case is assigned to Pond Naravit and Phuwin Tangsakyuen, two partners who have worked together for years, though neither of them has ever acknowledged the tension between them. They are joined by Perth Tanapon and Santa Pongsapak from the morgue. As the death toll rises, it becomes clear that this is not an ordinary series of murders. Something is calling them. And soon, Pond and Phuwin may be next.
