midnight
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 . _ 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 .
