The theme behind the novel “Hard Cash” seems to be what happens when a crook retires from the life and his past catches up with him. Nolan and Jon have had a few adventures together in the first four novels of this series (Bait Money, Blood Money, Fly Paper, and Hush Money). In this book, although Nolan and Jon are trying to play it straight, as they walk down the street, the dark shadows from their past are nipping at their heels.
