Dasha Vasilyeva is a plasterer by training; she’s often broke and lives on oatmeal! She has neither a family nor children—so, aside from a name, she has nothing in common with the well-known private detective fan. Yet Dasha still has to conduct an investigation—because how else could it be, if her new boss’s family was attacked by a real pestilence? It all started when Vladimir Speransky, a psychologist and an amulet-maker who hired Dasha as an assistant and, on top of that, as a housekeeper, had his wife drink a harmless mineral water—and she was poisoned. The soda was served at the home of an oligarch, Stebunkov, who recently had a similar story: he brought meat from Africa—meat of a crocodile he had personally killed himself—and fed all his friends with the treats. And among them was that very namesake: the great detective Dasha Vasilyeva!
