What is Dead Hour?
1.
The Hour between 3 am and 4 am. Called this because this is the time that the most people die in their sleep in hospitals. Significant because this is also the time that people are generally sleeping deepest, so things are quietest.
The robbers chose to wait till the dead hour to break into the store, because there would be no-one to see them, and no-one would wake up.
