A Witch's Business

In a small village near Tula, extremely strange things happen: a hen crows like a rooster, fresh milk turns sour, and rabid dogs attack people. At first glance, it may seem like nothing truly explainable—but there are too many incidents, and their number grows every day. Local officers from the OBKhSS—department for fighting chaos, monsters, and entities—call in Nikolai Dergunov for help. He investigates the case, but there’s nothing to latch onto: there’s no outburst of negative energy, and there’s no motive for the crime. But is it really that simple? Who is behind the so-called Witch’s Case—and will Nikolai be able to uncover it?
