It was a pleasant day, the roads were good, and they had a delightful trip to Menton. Bert and Nan were treated to ice-cream soda in a drug store while their father did what business he had to look after. Then they started back.
As they drove past the Menton railroad station Nan suddenly caught hold of her father’s arm and exclaimed:
“Look! There she is again!”
“Who?” asked Mr. Bobbsey.
“That old lady—the one with the faded shawl and the green umbrella—the old woman who left Baby May on our doorstep!” gasped Nan excitedly.
“Where is she?” her father cried.
“Look! She’s just getting on the train,” said Nan, for a train was about to leave the station.
“Oh, I see her!” cried Bert. “It’s the same old woman!”
“I must stop her! I must speak to her!” cried Mr. Bobbsey. “It’s lucky you saw her! I say there! Hi, madam! I want to talk to you! Wait a minute!” he called loudly, as he drove the automobile as close to the track as he dared go.
