The Red-Eyed Boy. The Flint & Locke Mysteries, #3

Death Comes to Those Who Look Upon the Face of the Red-Eyed Boy. Prominent men are dying across London, and no one can explain how. There are no signs of struggle, no visible wounds, and no clear cause of death. The only connection between the victims is a rumour spreading through the city's darker corners, that those who look upon the red-eyed boy do not live to speak of it. Inspector Morven Flint has no patience for superstition.
Yet as the deaths mount, even he is forced to admit that something about the case refuses to obey reason. At the same time, another terror begins haunting the streets of London. A terrified woman emerges from the fog with a name on her lips. Witnesses speak of a black-clad figure leaping across rooftops with impossible speed and strength. Spring-Heeled Jack has returned. As panic spreads through the capital, the two mysteries begin to blur together in the public imagination.
But Flint and the enigmatic Edwin Locke soon discover that the truth behind the red-eyed boy lies elsewhere entirely. Beyond the reach of the police, the ruthless Mordecai Shrike and his brutal lieutenant, Isaiah Ketch, are shaping a nightmare in secret: a strange and unnatural boy, silent and obedient, capable of moving where no ordinary man can go and killing without warning. Meanwhile, across the rooftops of London, an old legend is stirring once again.
As the city descends into paranoia and rumour, Flint finds himself trapped between myth and murder, pursuing enemies both real and seemingly impossible. The Case of the Red-Eyed Boy is the third instalment in The Flint & Locke Mysteries, a dark Victorian detective series blending murder, conspiracy, gothic horror, and the creeping fear of the impossible.
