“The Investigation Is Carried Out by the Half-Blood” is a novel by Vladimir Batayev and Alina Voronina. Genres: urban fantasy, detective fantasy. A star of “Elphogram,” which advocates for the rights of elf women, was killed. She is known under the pseudonym Caetana Isida. The girl is found completely drained of blood… But vampires don’t exist! Thirty-eight years ago, only orcs and elves came to Earth through portals! The investigation is assigned to the Department of Elven Crimes. But why does an employee of the Department—the one who is investigating—look almost exactly like the murdered woman, except for the shape of her ears? Because Lina is the only officially registered half-blood in the country. And her killed double is a human. Supposedly… To find the answers, Lina will have to work undercover in a sanctuary for elf women. And for that, it won’t be enough to hide the shape of her ears and change her clothing style—she’ll also have to imitate someone else’s worldview. And stop flinching every time she’s reminded that elf girls are “easy to access.” After all, the half-blood herself is very far from her sharp-eared relatives in this regard.
