Eddie 'Lucky' Brennan is a professional killer. A gun for hire who has been leaving bodies across Chicago for more than a century. Lucky's long life isn't an accident. It's payment. Saved from death by a demon from Hell, he has spent the last hundred years repaying the debt, with murders. Now the body count is rising, and the demon's ambitions have grown. This time, it isn't just about murder. It's about turning Chicago into the first foothold of Hell on Earth. Jack Nightingale is sent to stop the killings. But to bring down Lucky, he'll have to confront the demon behind him - and risk far more than his life. Because in the Windy City, there are worse things than dying.
