Persian Carpet is by far the worst game in the Sherlock Holmes series. Unlike the adventure games of the rest of the series, this title is a casual hidden object hunt. The environments and music are 100% recycled from The Secret of the Silver Earring, which came out years earlier. The pixel hunting is so extreme that you might as well be finding a needle in a haystack--from outer space. Seriously. The scenes are all zoomed out views of an entire room and the clues are things like "strand of hair" and "fingernail." I wish I was exaggerating. There's only one case and it's short and boring. The only somewhat interesting feature is the deduction board, where Holmes makes connections between different pieces of evidence, but it's so clunky and poorly formed that it loses all value. In fact, when I solved the mystery I actually thought I was stuck in a glitch until I randomly clicked the right thing to trigger the ending. And for reasons unknown, the ending fanfare music is "The 12 Days of Christmas."
I would honestly love to see a well-made and substantial hidden object game added to this series, but Persian Carpet is not it.
