John Tyler has a new mission: capture a heavily protected target from a ski resort in the Alps and smuggle him back to the UK.

The abduction was a success, and Tyler boards the Tiburon, a rusting freighter crewed by smugglers and mercenaries, for the last leg of his journey. But his mark's security team is hot on his heels, and won't be deterred by an ocean.

When Tyler's prisoner is found murdered inside a sealed hold on the ship, everyone on board becomes a suspect. In the flickering light of the Tiburon's passageways, there's nowhere to run but everywhere to hide.

Ronin meets Bond in this high-octane thriller with a locked-room mystery at its heart. Perfect for fans of Alistair MacLean.
