chunk: Ayrton's former companions arrive by chance on Lincoln Island, and try to make it into their lair. After some fighting with the protagonists, the pirate ship is mysteriously destroyed by an explosion. Six of the pirates survive and kidnap Ayrton. When the colonists go to look for him, the pirates shoot Harbert, seriously injuring him. Harbert survives, but suffers from his injury, narrowly cheating death. The colonists at first assume Ayrton to have been killed, but later they find evidence that he was not instantly killed, making it possible for him to be alive. When the colonists rashly attempt to return to Granite House before Harbert fully recovers, Harbert contracts malaria and is saved by a box of quinine sulphate, which mysteriously appears on the table in Granite House. After Harbert recovers, they attempt to rescue Ayrton and destroy the pirates. They discover Ayrton at the sheepfold, and the pirates dead, without any visible wounds.
