On one man in the group his eyes rested long and earnestly, although covertly.

"He's just about the build," Shadow mentally said. "And he tallies with the description."

With what description?

We shall see in due course of time.

"Shall I dog him?" thought Shadow, and then his eyes sought the floor and remained fastened there in a reflective way for some minutes.

The result of his reflections was apparent when, the man having left the saloon, Shadow followed him.

"I have been disappointed a dozen times," Shadow told himself, and then sighed. "If I am disappointed again it can make but little difference, for in the end I shall take a fitting revenge for that great wrong."

And Woglom, river-pirate, murderer, burglar, anything so long as it paid him well enough, was from that minute under the surveillance of as keen a pair of eyes as were ever set in human head.

The villain was one of the gang connected with the old sugar-house, and thither Shadow had tracked him.

The mysterious detective determined to secretly gain access to the place, though that would have been a task to appall the heart of the stoutest detective on the force.
