“What’s jaundice, Mother?” asked Nan, when the doctor was gone. “Did I ever have it?”
“Yes, you had it, and you turned as yellow as saffron, so Dinah said. As a rule, it isn’t anything serious. Little babies often have it. Their stomachs get out of order. But I will need to have this medicine brought from the drug store.”
“I’ll get it,” offered Bert.
“I’ll go with you,” said Nan.
“We’ll go, too,” chimed in Flossie and Freddie.
“No, it’s too late,” said their father, for, though it was not yet dark, night was fast coming on.
However, it was not too late for Bert and Nan to go to the drug store, which was only a few blocks away, and out they started. Bert had some money saved up, and he treated his sister to an ice-cream cone while they waited for the medicine to be prepared.
It was when the twins were on their way home that Bert saw Nan stop, turn around, and look back several times.
“What’s the matter?” he finally asked.
“I thought I saw some one following us,” she answered.
