Although Angelo's presence in the entire story is not prominent, it doesn't mean Angelo didn't leave any clues.
"If the stories in the rumors are true, then Angelo returned to the Manbadger family at least twice." Nis: "When the Silver Lady revived and at her funeral, Angelo certainly came back."
Angel: "I think, back when the Silver Lady was still Miss Silver, she was paralyzed and then recovered, which might also have been Angelo's doing."
Ironclad Granny nodded in agreement, "The Viscount's wife died suddenly, and rumors spread outside, yet this Viscount did not control the public opinion. It's very likely he didn't dare to, to give an explanation to someone he dared not provoke."
This person whom even the Viscount can't provoke is naturally the extraordinary Angelo.
Following this logic, regardless of whether the Silver Lady was paralyzed, the Viscount's wife's death is probably inseparable from Angelo.
