Three people followed Isidore and came to a section for history books, where they saw him walk to a nearby locker, enter the password to open the box, and then take out a small suitcase and stuff his own briefcase into it before leaving with it in hand.
As he passed in front of David, he gave a covert glance to David, implying that his mission had been accomplished.
In the time that followed, David and the others pretended to read books while keeping an eye on the locker, trying to see who would appear.
About twenty minutes later.
Under the watchful eyes of the three, a man around 18 or 19 years old, wearing a hip-hop hat, appeared.
He approached the locker, expertly entered the password, took out the briefcase, and casually walked off with it.
