The boys kept right on. They ran like greyhounds. But the police were fleet of foot, too.

They had passed the park now and were running through a street bordered with dark houses. Jack’s reply was startling.
“They’re police dogs!”
“Police dogs?”
“That’s right. They have them in New York, too, and I remember reading in the paper that they were imported from Belgium.”
Shouts came from behind them.
