章 398: 396 Guesses (Part 2)_1

"Mother..."

A touch of melancholy flashed in Isa's eyes, but disappeared quickly.

However, Colin caught it keenly.

No matter how Lady Sharon treated Isa before, even if she had tried to harm Isa, she was Isa's birth mother after all.

"How did mother die?" Isa tried to maintain her calm tone, but this only revealed her inner unrest.

"She was poisoned." Colin sighed, then said, "I have sent people to investigate who might have visited your mother's room last night, but, I'm afraid there may not be any results."

Isa nodded, understanding Colin's meaning.

She also knew that the two of them didn't pay too much attention to Lady Sharon's security before, after all, they didn't expect someone would attempt to kill Lady Sharon.

As things happened now, Isa realized something was wrong and asked, "Why would someone want to kill mother?"

"In the rebellion planned by the East, the Duke Miller and Lady Sharon were not included."
