He turned down a side street, and they walked for three or four blocks, at length coming to a rather darker street. Here Bristow slipped around the corner and motioned Dick to silence.

The footsteps of their pursuer came to their ears. He drew nearer. Bristow advanced close to the edge of the building.

“What are you going to do?” asked Dick.

“You’ll see,” was the brief response.

As the man came into view, Bristow suddenly struck out with his right fist, and the man toppled over.

Bristow turned to Dick.

“Come!” he said quietly.

With one look at the fallen man Dick obeyed, and they were soon beyond pursuit.

Dick had been taken by surprise by the suddenness of Bristow’s attack. Try as he would he could see no reason for it. He, as well as Bristow, objected to being followed, but Dick would not have taken such measures to elude his pursuer.

He followed his companion without a word, however, and soon they were back at the hotel.
