to follow it until I find the truth. Good-by.
Don't worry."

And Peter, with a last pat on the woman's shoulder and an encouraging
smile, went out of the door and into the house.

Eagerly Peter's imagination was trying to fill the gap in Jim Coast's
story, and his mind, now intent upon the solution of the mystery, groped
before him up the stair. And what it saw was the burning Gila Desert ...
the mine among the rocks--"lousy" with outcroppings of ore ... "Mike"
McGuire and "Hawk" Kennedy, devious in their ways, partners in a vile
conspiracy....

But Peter's demeanor was careless when Stryker admitted him to McGuire's
room and his greeting in reply to McGuire's was casual enough to put his
employer off his guard. After a moment's hesitation McGuire sent the

McGuire had started forward in his chair, his face livid.

"You know----?"

"Yes. More than I wanted to know--more than I wou
