"You have given me extraordinarily valuable information, Miss Jamison. I shall see that it reaches the War Department at once. I have always insisted that women make the best members of the secret service. But under the circumstances I feel that I have the right to tell you this. We did know something of this plot you have just unveiled. What we did not know was where to find the centre of the conspiracy in Coblenz. I think you need have no uneasiness, the Kaiser will never be saved from the consequences of his acts while the allied armies are policing the Rhine. However, Miss Jamison I am glad to have had you in Coblenz and think you have justified your coming to Germany. May I congratulate a Red Cross girl for another variety of service to her country. Now you are tired, shall I not send you back to the hospital in my car?"
But Sonya Clark shook her head.
"No, thank you, Colonel Winfield. Dr. Clark is to have one of the Red Cross automobiles come for us, which is probably now waiting around the corner. We wished our visit to you to be known to as few persons as possible. Major Hersey will see us to the car. Goodby."
CHAPTER XXI
The Rainbow Bridge
ONE afternoon in May, Sonya Clark was entertaining a number of friends among the American officers and soldiers in Coblenz in the garden back of the American Red Cross hospital.
During the early spring the Red Cross girls had devoted many leisure hours to digging and planting flower seed on the level space just behind the old building and overlooking the banks of the Rhine.
This afternoon this spot was gay with spring flowers, also there were old rose vines climbing high on the grey stone walls, now a delicate green but promising a rich bloom in June.
