When a woman disappears, a homeless man is the only person who can find her. On a cold Manchester night, Victor Mitchum and his loyal-ish dog witness something they were never meant to see. Living on the streets has made Victor good at watching people—which is exactly why private investigator Kasper Dabrowski recruits him to help find a missing woman. But as Victor watches from the shadows, he realises he has stumbled into something far more dangerous. Working alongside Kasper and his sister, Victor discovers he’s not just tracking kidnappers—he’s watching killers. And now they know someone is watching them. With time running out for their victims, Victor must rally his unlikely allies—the forgotten people of Manchester’s streets—in a desperate fight for survival. But in a city where the powerful prey on the vulnerable, can a man society has chosen to ignore become the hero these families need?
