Jack the Ripper in Children's fiction...what next?

After todays session I went away to research how Jack the Ripper has been exploited within literature and different types of literature used. I was very shocked in how many different search results I pulled up just from looking at Google's search results. After spending a lot of time searching through lots of different websites I found some very interesting results under the topic: Children's literature. It shocked me that such a brutal subject has in fact been turned into a book in which a child may engage with. In my opinion I think that the author may use Jack the Ripper as the main subject as it is a universally known subject which pulls in a certain audience especially when it comes to the horror genre, whether it be adult or children's fiction.

One of my most interesting finds was Darkside by Tom Becker. Here is a link to give you the main idea of the book:

I was interested to see how the author had adapted such a gruesome idea into a Children's horror book. The main character in this book discovers a place where Jack the Ripper's children rule. I think that in context it is quite a strange subject matter to include in a children's book, but maybe it is a topic that has become a lot less fact and a lot more fictional since it was such a long time ago.
