Matthew nodded.
He believed Zeller.
"If the three major organizations only mentioned the time of their attack in their letters, then where did you get the detailed data on their number of members, their position structure, and their estimated strength?"
Matthew pointed at the rows of numbers on the report.
"That was the work of divination and scouts."
Zeller explained,
" There have traces of any unusual movements. Actually, before I received the letter, I had already sent scouts to the surrounding cities to collect information. At that time, I found some clues. It is impossible for such a large number of people to move quietly. They need food, accommodation, and equipment."
Matthew looked at him curiously." How did you think of sending people to other cities to investigate?"
Zeller explained patiently, "For that, I have to mention the case of the mole that I was commissioned by Rheagar to investigate."
