In what way is the island of Nevis an important setting in the novel, Blood on the River?

Nevis is the island paradise where the settlers stay for six days, and where Samuel and the other servant boys enjoy swimming in the ocean and eating fresh fruit. Richard and James never want to leave the island because it is so pleasant there. Nevis is also the location where Wingfield and the other gentlemen try to hang Captain Smith but change their minds after persuasion by Reverend Hunt.
