Bain: Guys, I'm sorry but the end of summer vacation.
Yesterday, through hidden cameras, I noticed that some security guards came into my estate
and stolen my money.
Fortunately, one of my man was there and  placed a tracker
their truck. My man followed them and is in the middle of the city
they led to a huge estate. They went out and heard my man
they say, "Take the Hall E section".
Later, he saw a lot of cops, and he seemed very suspicious. He decided to use drone and look around.
He has found  Hall A to D, but that is Hall E, not yet.
There is Hall E section, but then where is it? And why is it all
at night there are so many cops in that estate? Guys ... get it back
my money and explain this puzzle.
