An archaeologist was found dead in a sealed tomb. The cause of death was dehydration. Her canteen was full, and a candle was burning brightly on a pedestal. Detective Cross arrested her rival outside. How did Cross know the tomb was never truly sealed?
The burning candle
Fire requires oxygen to burn. In a truly airtight, sealed tomb, a burning candle would quickly consume all the oxygen and extinguish itself within minutes.
