"What?" The woman suddenly asked Lyle with a nervous smile.
"What are you talking about Ned, what poison?"
"Drop the act, Diana, I know you poisoned it before I even entered the room."
"The poison in the wine is odorless, but unfortunately for you and for those that orchestrated all of this, the color of the wine changed slightly, not to mention the thin green line that can be seen on the edges of the wine bottle from the poison that had touched it."
"It's still not a bad idea, you took the antidote in advance so that you could drink the wine and make me feel comfortable with drinking it."
"You used a poison that lasts for a long time, probably Manderbush or even Liang, both of which are not that easy to make nor are they readily available to everyone, which makes me certain that you were not one to buy it, you don't have the money, nor the connections needed to get it."
