If this kind of effect can be replicated in France, then Gasoline is practically getting a free Scott. He can't imagine a reason to refuse Arthur Sigma's work; publishing his works certainly involves some risk, but the rewards are quite substantial.
Moreover, according to some rumors Gasoline received from London, Arthur Sigma himself has long served as a high-ranking officer at Scotland Yard. Combined with the "Hastings Case Files" and Mr. Arthur Hastings' personal experiences, his true identity is actually not difficult to guess.
Compared to the small risk of not publishing Arthur Sigma's works, Gasoline is even more unwilling to bear the major risk of offending the big shareholders of the "British", the former high-ranking Scotland Yard officer, and the publishing review committee.
In other words, even if Arthur doesn't mention it, Gasoline will shamelessly offer a lucrative contract to Arthur Sigma.
