Kosher sushi, kebabs, a second-hand bookshop and a bar: the 19th arrondissement in Paris is a cosmopolitan district where multicultural citizens live, love and worship alongside one another. This peace is shattered when Ahmed Taroudant's melancholy daydreams are interrupted by the blood dripping from his upstairs neighbour's brutally mutilated corpse. The violent murder of Laura Vignole, and the pork joint placed next to her, set imaginations ablaze across the neighbourhood, and Ahmed finds himself the prime suspect. But detectives Rachel Kupferstein and Jean Hamelot are not short of other leads. What is the connection between a disbanded hip-hop group and the fiery extremist preachers that jostle for attention in the streets? And what is the mysterious blue pill that is taking the district by storm? Karim Miské demonstrates a sharp eye for character and an evocative sense of place, moving seamlessly between the sensual streets of Paris and the synagogues of New York to reveal the truth behind a horrifying crime.
