Over the course of telling you about my case files, I've mentioned some of the other cases I've looked into, but haven't had time to put into books for you.
Here are the case names, but what do you think the cases were about? Email me and I'll get Muddy to put the best ideas up on this page. You could always write the story behind the title if you have a really good idea!
The Twisted Sparrow
The Mystery of the Sleeping Cactus
The Adventure of the Impossible Hamster
The Martian Cyclist
The Case of the Shrinking Monkey
