"Their tail light!" cried Dick.
"Unless it's some other car," said Paul.
"We haven't passed any, though maybe we're catching up to one that came in from some side road," admitted Dick. "Here goes for a spurt. Maybe we can catch 'em!"
He threw on all the power that was safe on such a road at night, and the Last Word forged ahead. It was their one best chance to catch the other car, if indeed that was it, and they were taking advantage of it.
On and on they raced, the big auto swaying dangerously. Fortunately they did not have to worry about tire trouble, and this was something that might handicap the other car at a moment's notice. On and on they raced.
"The light seems to be brighter now," said Paul.
"I think we are catching up to them," agreed Innis.
"I hope so," murmured Dick. He peered ahead for a sign of any possible obstruction into which they might crash. At the speed they were keeping up, to hit anything, or have even a slight accident, would be serious. But the big lights made the road very plain.
"They must have seen us," observed Paul.
"I fancy so," agreed Dick. "I wish we had some way of puncturing one of their tires."
