The plane crashed, but all five people on it survived. Yet now, on the desert island, they have come to a horrifying realization: The only boat fits only four people. One must be left behind. They decide to vote who will be left behind, but first they want to get to know each other. They believe it will make deciding easier.
It turns out that each person is really very admirable – just the sort of person who ought not to be left behind. To make the decision harder, each person also has a skill that would make them very valuable on a life raft at sea.
But as the discussion progresses, it becomes clear that each person also has a secret in their past. One person was a thief, another abandoned a young family. But then they learn that one of them has a history of not returning library books until well past their due date, in some cases even flipping upside down the little “Due Date” card so that the book appears not to be due for six months. Unable to abide such deceit and lawlessness, the rest decide that the library fiend must be left on the island and try living solely on coconuts. Using only the information below, can you determine who is the library fiend who will now be abandoned?
