There, they meet Sir Francis Drake, who is preparing to launch a daring expedition against the Spanish, which could turn the tide of war. Unbeknownst to Bruno, however, Sidney plans to stowaway with Drake's fleet and return a hero – dragging Bruno with him to the New World. But when a murder occurs aboard Drake's own ship, fear and suspicion grip the fleet and threaten to abort the expedition before it begins. Navigating the jealousies and loyalties of the crew, Bruno learns that someone with a deadly grudge is shadowing his investigation. Tracking the killer through Plymouth's menacing backstreets, he uncovers some of the darkest secrets the city is harbouring. Failure will come at the highest cost – not just for Bruno, but all of England…
