Detectives

1. One volunteer is the detective and goes outside. You give a coin to one of the students in the class to hide on their person - he or she is the thief.
2. The detective returns and accuses any member of the class: 'Did you take the money?' The accused, whether guilty or innocent, answers, 'No, I didn’t take the money, X (names one of the others) took it.' The detective then accuses X, using the same formula as before, and so on, until ten or fifteen people have been accused. The detective watches the accused people and has to try to 'detect' by their behaviour, which one is lying. Give him or her three 'guesses'.
