"Casual" giant PopCap Games continues its detective-themed hidden object series with a trip to Europe in Mystery P.I.: The London Caper. Players travel to the home of Big Ben at the behest of the Royal Family after the famous Crown Jewels have been stolen. Gamers have just 17 hours to search through 25 different settings, with more than 2,000 hidden items offering clues to the location of the purloined treasure. Each scene features a secret object worth one million bonus points, while hidden keys and crowns unlock two unlimited game modes, and nine mini-game puzzles offer a respite from the hidden object gameplay.
