They call in CHERUB a secret organisation with one essential advantage: even experienced criminals never suspect that children are spying on them. James' latest mission looks routine but the plot he begins to unravel isn't what anyone expected. & 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.
