The Butterfly Farm falls in line with all the other predictable adventure books. I say adventure because it was no mystery to me. The title of the book made no sense.
It's about a widow who's part of an cruise touring Central America. Her husband has died recently, and she's trying to recuperate with her friends. Then they suddenly find a dead body aboard (sound familiar?) with a blue butterfly beside it.
Several suspects are introduced, mainly a "nice" man and a "mean" man. Of course the "mean" man, who is an upstanding citizen, blames it on the "nice" man, who has a checkered past. But of course our lead knows who it really is.
Most of the plot is trying to be funny and it doesn't turn out to be funny at all. The characters are average, about as average as possible.
But the final scene is the icing on the cake. Hostages being miraculously rescued at the last possible minute is really ridiculous. The whole idea of the book has been used before and worn out. It's probably not worth your time.
1.5 stars because this idea has been overused
