Barking up the Wrong Tree - An Object "Fanfiction"

Tree is a private investigator in the busy city of Mergerville. So when Apple turns up dead, and the police turn a blind eye, it's up to Tree to find the culprit. Meanwhile, more and more incidents start popping up at an alarming rate. Can Tree solve the mystery before it's too late?

This is the first story I have ever written that is longer than 3 pages. Subsequently, this is the first "Fanfiction" I have written. Appreciating feedback and/or ideas seems to be a common theme with this sort of thing, so feedback and/or ideas are appreciated.
