On the way back, two extra couples have joined the group. Luckily, the boat has been upgraded and can now accommodate three passengers at a time. Sadly, the wives are just as suspicious as before. How can the group cross?
In another presentation of this puzzle, the couples are replaced by pairs of knights and pages. Any page left in the company of another knight, without his own knight to protect him, would either be killed or would die of fright.
