He is in a secret underground chamber, protected by a security system. You need to beat all of the Game Shows before you can get to him.
1) When you beat all of the game-shows, you go back to "Main Street" to talk with the inventor. He gives you a thumb drive that can reprogram Holmes.
2) You need to get past 4 security screens to find Holmes. They are sliders puzzles where you create a complete path from input to output (they are pretty easy if you know what you're doing).
There is a clue that makes this easier: each of the squares has a colored edge where it meets another square with the same colored edge. Match the colors (top to bottom, side to side) and you will have them in the right location.
3) You find Holmes and then you plug in the thumb drive. Holmes is reprogrammed into a friendly computer again. You receive the island medallion from the Inventor.

You have to beat all 5 game shows, then return to Main Street to find Holmes. Except for the Tokyo game, you are returned to the street to take your jet to the next place. On Mr. Yoshi's show, click the background after you have won the show. (see related question)
You only get to Holmes after you beat all 5 game shows, then avoid his robots to reach the sewer entrance on Main Street. Beat 4 of his security systems, and you can use the Inventor's thumb drive to reprogram Holmes to be friendly again. (see related question)
The inventor goes near Holmes (underground), so when you see pst... in here! or something like that,that's where the inventor is (this is main street for your information in poptropica).
