Tina's eyes widened in disbelief, her face draining of all color as she stared at Anna. How could she possibly know?
Impossible!
Their mother had been extremely cautious, and the person who'd been poisoned was long dead, there shouldn't have been a single clue left behind.
Tina quickly composed herself, clenching her fists so tightly her knuckles turned white, then forced out a calm voice. "Sister, what are you talking about? I don't understand."
Anna's gaze stayed locked on her, sharp and steady, easily catching the flicker of panic that flashed across Tina's face.
"What? Didn't you just say you didn't understand? Then why do you look so nervous?" Anna asked, her tone light yet piercing.
Tina froze, realizing too late that Anna had deliberately set a trap for her. She'd just exposed herself.
Straightening her posture, she forced a calm expression and shook her head. "I'm not nervous."
