Early morning.
Outside the investigation bureau, a shabby-looking, bearded, coughing middle-aged man nervously approached the front gate, "Excuse me...is this the investigation bureau?"
"Who are you?"
The security agent at the door was on high alert. Not many people would know the address of this confidential unit, and this man didn't seem to fit the bill.
"A mysterious person asked me to deliver this note to you, saying that you will understand once you see it...cough, cough..."
The middle-aged man coughed a few more times, passing over a note.
The investigator carefully took it, his expression dramatically changed after scanning it. "Come in with me!"
...
After a moment, outside the interrogation room.
Jacob held the note in his hand, a playful smile on his face, "Is this from the same mysterious person who gave us Roberts' location last time?"
