Detective Dudes : Neil’s Revenge
Neil Daniels who, by the age of ten, is already a Oxford graduate school student and has developed a DNA Tracker software. Neil now in the final stage of his second major work, an artificial intelligence system called Krogos, in a heavily guarded room. Neil has been under the guardianship of Thomas Chappel, owner of the software giant Sunbird.Inc., since his mother died. He has been put under a rigorous study program and has a somewhat deprived childhood. One night, at the top of the Sunbird building where Neil lives, Neil finishes Krogos, sending the software through the telephone lines and after, his computer shows the message "Krogos Sailed Out." The security guards become suspicious and try to enter Neili's room. When they finally break into Neil's room with Chappel, Neil is not in the room. He leaps off the top of the building to his death. The image on his computer screen shows an ark sailing in water and the words "Good-bye Neil"
Two years later, at the City Hall, Sunbird, Inc., holds a demonstration of a virtual reality game system called Cocoon. Many kids, including the Kimi Mattews, Olivia, Troy, Alex who call themselves “Detective Dudes:” are invited to the demonstration. However, only the kids with badges are chosen for the demonstration. Doctor Matt and Jimmy Mattews (Kimi’s father who is a famous Detetive) arrive at the City Hall. Dr.Matt gives Kimi Mattews a badge and tells Kimi that his mother, Vivian Mattews, would not be there because of an alumni reunion. The rest of Detective Dudes trick a few kids by exchanging badges for the Premium Pokemon Cards. They all use the badges and participate in the demonstration.
In another room, Duke Osbourn , one of the designer of Cocoon, is murdered. Osbourn's types in a dying message: the letters J, T and R. Kimi discovers the murder and decides to participate in the demonstration, hoping that the game would lead him to an answer. Jimmy Mattews finds out that J-T-R stands for "Jack The Ripper".
When the demonstration begins, Neil's artificial intelligence system, Krogos takes control of the game system Cocoon and tells the audience in a metallic voice “if all fifty kids in the demonstration lose the game, it will kill the kids with a large electromagnetic burst. The kids in the demonstration are given a choice of five stages in the game”
Kimi and the Detective Dudes choose the final stage, a re-creation of an 1800 London mystery.
It was almost accurate recreation of 1800 London with smog all around and suddenly Detective Boys hear a scream of Jack The Ripper’s fourth victim and they rush toward it. Kimi discovers that Dr.Matt's inventions don't work. Kimi and his friends track down 221b Baker Street because Kimi think that his had who Designed the levels of Cocoon was a Sherlock Holmes fan would not develop a 1800’s London without Holmes. But they find that Holmes and Watson are at Dartmoor. However Holmes was supposed to be there. Jimmy discovers that Krogos has edited the Londen Level.
