The Truth

A motionless shadow made with a human-shaped object and a light

The answer is "A motionless shadow made with a human-shaped object and a light."

He died before 9 p.m., yet the shadow was cast from 9 p.m. all night. A motionless shadow can be made with a dummy and a light. The culprit staged it so that he seemed to be alive at 9 p.m.

Since he died before 9, "the resident did not move" cannot be right. Nothing says a tree outside or another person would take the shape of someone at a desk.

What the unmoving shadow wasLampDummyCurtainStill shadowA person-shaped object and a lamp make a still shadow, so that thevictim seemed alive at 9 p.m. although already dead.

Key Points

  • Focus on the gap in the times
  • Think of the lack of movement as unnatural
  • Think of a method of staging it

Why people get fooled
