"We'll beat the car they're in by taking the elevated," said the old
detective as he dismissed the cab. "Up at the stables we may learn which
car passed Grand street quarter of an hour ago."

"It's worth while trying."

So up they went.

When they reached the stable, they were disgusted to find that the cars
which passed the corner of Grand and the Bowery about the time the
smugglers boarded one, were all gone ten minutes before.

But one more course was open to the detectives.

That was to proceed to Harlem bridge on the elevated and make another
effort to head off the fugitives at the terminal of the road.

Once more they started.

Each defeat whetted their appetite more to capture the fugitives.

The elevated cars passed many of the surface cars, and when the 129th
street station was reached, they went down to the street.

Just as they were about to start for the surface cars, to begin making
inquiries, Harry glanced over at the Harlem bridge.

To his surprise and joy he saw Clara and the four spies hurrying over the
structure on foot.
