Had Colton succeeded?
He thought of riding to Nyland's ranch, but he gave up that idea when he reasoned that perhaps Colton had failed, and in that case Nyland wouldn't be the most gentle person in the world to face on his own property.
If Colton had succeeded he would find him, in Okar.

So he mounted his horse and rode to Okar.
The town seemed to be deserted when he dismounted in front of the City Hotel.

He did not go inside the building, merely looking in through one of the windows, and seeing a few men in there, playing cards in a listless manner.

He did not see Colton.
He looked into several other windows.

Colton was nowhere to be seen.
In several places Dale inquired about him.
