An astonishing historical tale of love, treachery and piracy. First, this confirms many people's long-held beliefs that mermaids really do exist. The obvious problem is surely in how they procreate and reproduce owing to the slimey wet fish body from the waist downwards. This is doubtless why there are so few of them and like Murray, people need to turn into fishy people to be able to get close to these mermaids. So being a fishy person is no bad thing unless one goes too far and then ends up being a praetorian. Yes, it's all here in this tale (or should that be 'tail'?).
