DETECTIVES: At the party some girls secretly fill in the questionnaires on index cards. In these questionnaires the girls indicate their distinctive marks: height, color of the eyes, dress cut, jewelries. The leader puts all the cards into the box. Between the dances, the leader asks the most attentive boys to act as Sherlock Holmes or Hercules Poirot - to find a girl with help of the description given in the card. The boys take the cards and begin to search for the girls. The boy who finds the girl the first is the winner. Then the boys have a dance with the girls they have found.
