When James Mycroft drags Rachel Watts off on a night mission to the Melbourne Zoo, the last thing she expects to find is the mutilated body of Homeless Dave, one of Mycroft’s numerous eccentric friends. But Mycroft’s passion for forensics leads him to realize that something about the scene isn’t right, and he wants Watts to help him investigate the murder. While Watts battles her attraction to bad-boy Mycroft, he’s busy getting himself expelled and clashing with the police, becoming murder suspect number one. When Watts and Mycroft unknowingly reveal too much to the cold-blooded killer, they find themselves in the lion’s den, literally. A trip to the zoo will never have quite the same meaning to Rachel Watts again.
