ou dial Dr. Susan Lydell and she picks up instantly.

"I hope you've figured out what source of disease Isabella and Troy have in common," she continues. "We're having a hard time here. Do you have a list of suspects?"

Quickly you run through the possibilities:

• It's the houseplant
• It's the spider bite
• Exterminators caused it
• It's something in the milk
• They got the disease from the family pet
• It's from the bloody tattoo
• It was in the hot dog
• It was in the pizza
• The mushrooms are toxic

"So which is it?" she asks. "What made them both sick?"
