Sherlock
As Sherlock goes around and searches the clues, every player tries to remember each of the eight objects hidden in a facedown circle of cards.  Then, Sherlock travels from one card to another.  Each time Sherlock stops at a facedown card, the player has to remember which object is on that card.  Sherlock continues to move, as long as the player guesses correctly.  If Sherlock travels to a face-up card, then the player gets to keep that card. The first player to collect six cards wins!
