Whether this pack is real or fake, people on here are forgetting that the game Clue exists. It's a murder mystery and is for people ages 8 and up. The film based on that game is rated PG. Assuming the Sims did a murder mystery, the actual game play would likely be similar to Clue. It probably wouldn't show the person getting murdered unless it was a poisoning. The animation would be similar to the Sims 2 when your sim would get so tired they'd fall face first into their food. I can't see this being an EP. It would be better suited as a GP.
On a side note, EA Mobile produced a Clue game in 2009. The description from Wikipedia: "Rather than being a board game, Clue played out more like a simple point-and-click game where the player traveled around the rooms from the mansion to collect clues from the 6 suspects to decipher whodunnit. Each case was time limited, and every action taken used up a set amount of time. Successfully making a correct suggestion within the allotted time gave the player the maximum 4-star score for the level. The player character is a reporter who has to get the top story to solve a case, and get a promotion."
