"No, that's not true, Dave!" Freddy Farmer spoke in his ear at that moment. "I'm the thoughtless blighter. Don't you remember? I began carrying that letter at Puerto Rico. I confess I had forgotten all about the blasted thing."

Dawson looked hard at his pal and then shrugged.

"Okay, you or me, what does it matter?" he sighed. "The major should be plenty sore at both of us."

"You can skip that, both of you," Major Parker spoke up instantly. "After all, maybe it's a break in a way. The rat is dead, and that makes one less of his breed to bother us. Ten to one he killed that field laborer and searched my office. If so—"

The major let the rest slide, for at that moment all heard the roar of an approaching aircraft. It was coming in fast from the north, and as Dawson stared in that direction, he caught sight of the winking green and red running lights. A couple of moments later, the field lights were turned on to light the long runway. Shortly after that an American B-25 slid down to a nice landing, and went trundling over toward the Administration Building. Dawson, glancing at his watch, saw that it was exactly midnight.


CHAPTER TEN

Invisible Eyes

No sooner had the North American B-25 bomber braked to a full stop in front of the Administration Building than the fuselage door swung open and Colonel Welsh disembarked. The Intelligence officer's thin face was deeply lined from worry and loss of sleep, but his eyes were sharp and clear as he swept them over the group that had sprung to attention. When his eyes came to Dawson and Farmer, a light of relief seeped into them, and he gave a little nod of his head as a sign of recognition, and perhaps approval.
