The Killing (Cherub)

Leon is a small-time crook who's ridden his luck for three decades. When he starts splashing big money around, the cops are desperate to know where it came from. The call in CHERUB, a secret organization with one essential advantage: even experienced criminals never suspect that children are spying on them. James' latest mission looks routine: make friends with Leon's kids, infiltrate his home, dig up some leads. But the plot James begins to unravel isn't what anyone expected. And the only person who might know the truth is a reclusive eighteen-year-old boy. There's just one problem. The boy fell to his death thirteen months earlier.
