Death. A castle. A posse of cats. Rosie isn't sure what to expect when she gets an invitation to Carlyle Castle. The castle has stood in the heart of the Australian countryside for years, inhabited only by its reclusive owner, Alex Carlyle, and his two servants. Alex is convinced that one of his children want him dead. The question is - which one? Alex wants Rosie to watch and listen when the family come to visit, but all does not go to plan, however, when death strikes unexpectedly. To make matters worse, the murder is an impossible crime, committed in a room locked from the inside... At the same time, movie making is happening in Cape Carson, and involves plenty of feline actors. But everyone's not happy. Some people think that cats and movies don't mix, and is desperate to get the movie stopped - even if it means that someone has to get hurt! Rosie's best friend, Kim Chen, wants a role in the movie. And a lack of talent or experience shouldn't be a hurdle. Should it?
