Oliver drank the entire bottle without trouble.

Everything seemed normal.

Yet the baby kept losing weight.

Isabella scanned the room carefully.

Her eyes landed on a glass of water beside a chair. At the bottom was a faint white residue.

“Whose glass is that?” she asked casually.

“Mine,” Maria said. “I get thirsty while feeding him.”

Isabella picked it up and smelled it faintly.

A subtle medicinal scent.

“May I take this with me to analyze?”

Richard laughed dismissively.

“Now you’re investigating a glass of water?”

Isabella remained calm.

“I need to eliminate unusual possibilities.”

Then she asked a difficult question.

“Is there anyone in the house who might want to harm the baby?”

The silence was immediate.

Richard’s voice dropped dangerously.

“What are you suggesting?”

“I’m saying that a baby who eats well but loses weight usually has a medical explanation,” Isabella said carefully. “But if every test is normal… we must consider other possibilities.”

Natalie covered her mouth.

“You think someone is poisoning him?”

Richard exploded.

“That’s absurd!”

But Isabella noticed something strange.

For a brief moment Natalie’s expression changed—not to horror, but to fear.

Not fear for the baby.
