3D puzzle on a CD

About a year ago I purchased a CD puzzle. It is called Victorian Mansion. You build a 3D picture of a mansion. Once you complete building the mansion, you are allowed to enter the mansion, move through all of the rooms to find clues to a murder. The puzzle is made by the Wrebbit Co. in Canada. That is the same company that makes the regular 3D puzzles. I have built the mansion several times but was never able to find all of the clues necessary to solve the murder.
If you like building puzzles and solving mysteries, it a great game.
