Sharon Mansion had already been destroyed, so there were no clues left to be found. However, Owen Bertram hypothesized that there might be a ledger in East Prison Town Comfort Office. This is the unwritten rule among the corrupt officials: they would mutually blackmail each other to gain trust.
The profits from Perry Ronald's human trafficking in Sharon Mansion were most likely gifted to the higher-ups in East Prison Town, including Lin Ronald.
The ledger would record these transactions.
This ledger now became the sole clue to uncover the human trafficking trade. Owen Bertram interrogated the Seventh Prince and was sure that it did exist.
"Fine," the Seventh Prince reluctantly agreed, "I'll talk to Lord Ronald, but after you finish reading the ledger in front of me, I will take it back immediately."
"As Your Highness wishes." Owen Bertram laughed in response, "I will now eliminate the treacherous Julius for Your Highness!"
