When Poppy Fields and best friend Graham go on a weekend trip to the zoo, it soon becomes apparent that the staff there are not happy. Then one of them suddenly dies. And then another. And another... Someone's using the animals to do their dirty work for them, and the result is not pretty. Will the intrepid pair uncover the murderer before they, too, become dead meat?
