“Now, here’s my plan for catching him,” said Earl. “We will wait for the report of the patrol which is just starting. That will give us the location of any new fires. Once we plot them on the map, we can make a guess as to the place where he will probably start the next one. We can get there by plane almost as soon as he can by auto. Accordingly, if he works true to form, we will catch him in the act. That is, of course, providing that you are willing to fly low enough to see a single man running along a road.”
