The next day, Aiden read a letter from Heinz Hoffman.
Heinz had long since left the autonomous region, but he had left enough personnel behind to maintain contact with Aiden. Through the secret police's telegraph lines, they could establish rapid communication.
All Aiden had to do was to find a contact person and pass on a message, and the other party would relay the inquiry to Heinz. Then Heinz would issue orders to the secret police branch in Sunset City, and the Silvertown contact person who received the telegraph reply would disguise the intelligence Aiden wanted as an ordinary citizen's letter and deliver it to the warden's mailbox.
Just yesterday, Aiden passed a message to the contact person. He wanted to probe into the intelligence regarding the Revenge Temple mercenary group active on the southern border of Gistas.
Before that, Aiden also tried to ask Sophie for specific intelligence on the Revenge Temple.
