How to put it together

  1. Person 1 puts on the long coat and hat.
  2. Person 2 wears the dark suit outfit with shades.
  3. Person 3 wears the striped top and black trousers with a mask.
  4. Person 4 drapes the sheet, then the crew pose in a lineup.

Two variations

  • Cold Case Team

    Add magnifying-glass props made from card, plus notebooks and a paper map.

  • Comedy Caper

    Give everyone oversized glasses and exaggerated sneaking poses.

Safety note

Cut the sheet eye holes big enough to see clearly and keep the hem above the ankles. Check masks and sunglasses allow enough vision, and stay together near roads at night.
