But Van did not notice him. The boy's eyes were riveted upon the back of a man who was just entering the door of a saloon.
As he passed through the doorway the object of his gaze turned his head around for a single instant.
"That's the murderer!" exclaimed Van, and with a single bound he sprang from the car platform into the street, leaving the driver staring at his retreating form in blank amazement.
Van was satisfied that the man he saw was Doc Clancy, alias John Moreland. He had the features and general appearance of the villain stamped too deeply upon his mind to be deceived.
With a bound he dashed upon the sidewalk, nearly upsetting a passer-by, and then hurried into the saloon.
It was just after six in the evening, and the place was crowded with a set of laboring men who had stopped in to quench their thirst on their way home from work.
As the bar was but a small place, Van had great difficulty in squeezing through the motley gathering.
The boy did not notice the rough looks that were bestowed upon him as he elbowed his way through the crowd toward the rear of the saloon.
He was bent upon finding his man, and he forgot all else.
Van was young and impulsive, and he made a great mistake when he entered that saloon upon the errand he was bent, as he afterward found out.
