The spies evidently not knowing they were followed had driven their car up into a road leading to a hill overlooking the water. Von Papen and Boy-Ed were making the necessary connection of the wireless that would enable them to catch the messages at sea. Von Igel, with the driver, was standing guard. Suddenly Von Igel uttered a warning shout. Explanations were unnecessary. A glance below showed that they were discovered. Von Lertz, followed by Von Papen, leaped into his machine and swung into the road, followed by Von Igel in the wireless machine. With roaring exhausts they raced for the broad road that led to the city. Behind them, swinging and swerving, thundered the car carrying the Secret Service men. Far away Dixie Mason, driving leisurely, heard the sounds of the race. The hills resounded with the heavy echoes of the pounding machines. As she reached the crest of the hill she saw them below her. A small stream which was crossed by a bridge lay at the foot of the hill. As Von Lertz struck the bridge his car leaped into the air, wavered a moment and then crashed ahead, over the bridge and with a grinding of brakes, up the side of the embankment. Then Dixie gave a cry of horror as Von Igel's heavy car following struck the edge of the bridge as Von Lertz's had done, but with less luck, for the car swerved, skidded, swung about, and then striking the heavy cement railing of the bridge, capsized, pinioning Wolff von Igel beneath it. A moment more and a flame shot high into the air as the gasoline tank exploded. Von Lertz and Von Papen worked madly, endeavoring to extricate Von Igel from the wrecked car. She could not see the driver. Dixie peered beyond them. In the distance she could see the car which should have carried her Secret Service co-workers to the successful climax of this affair, stalled, its erstwhile occupants working in vain endeavors to start it. Dixie groaned. After all, it was up to her. Well acquainted with the character of the men whose schemes she combatted daily with a wit equal to theirs but with less resources to forestall, she summoned her courage and thoughts to do her bidding. Through fate, luck, she knew not what, her plan was endangered. And then this same fate played into her hands. As her car slid slowly down the hill, Von Papen spoke quickly to Von Lertz. "Do you know who this is coming down the hill?" Von Lertz glanced up. "No, but we passed him back in town. Why?" "We can use him--if he is all right. You and Boy-Ed take Von Igel in your machine and get him to a hospital quick. I'll have to try a rather dangerous stunt--work the Fifth Avenue wireless. It's risky but----" Dixie had brought her machine to a standstill near the smoking wreck of Von Igel's wireless machine. Her heart pounded madly as Von Papen stepped toward her. Was fate favoring her? It seemed so!
