“Get back in the cabin. We’re going down,” he said curtly.

Sue watched the altimeter.. The needle dropped gently from the 3,000 feet at which they had been flying, but the wall of fog still enveloped the earth.

They nosed through it carefully, the air speed cut down to a hundred miles an hour. Even that speed was a terrific one at which to crash into the ground. Sue was too busy thinking about her passengers to sense her own emotions.

For five minutes the pilot groped his way down and suddenly the nose of the big ship shot through the fog. The plane flattened out 200 feet above the ground and skimmed along over farmhouses with the motors roaring heavily.

Suddenly the ship heeled over and for a sickening instant, Sue thought they were crashing until she caught sight of an airport and knew the pilot was sliding in for a fast landing.

As the plane touched the ground the motors sucked the last fuel from the tanks. The tri-motor rolled up to the hangar and Sue looked at the name painted above the large doors. They had come down at Joliet, nearly thirty miles south of their course.

The pilot came back.

“Weather’s still bad around Chicago,” he announced. “We’ll have taxis here in a few minutes to take you in.”

Sue helped her passengers collect their hand baggage and sheperded them into the taxis. In half an hour the last one was safely away for Chicago, and Sue had time to sit down and have a little cry all by herself.

They remained at Joliet until mid-afternoon, when the fog cleared and they hopped the short distance to the field at Chicago. It was then that Sue learned that the second section of the Night Flyer was down at Sterling, Illinois, with the weather west of Chicago still foggy and little chance of it clearing before mid-evening. Sue could imagine the wrath of Mattie Clark, who had been anxious to reach Chicago that morning.
