“So I observed the other day. I don’t know about finding another car for you, but in any event I will see that you and Miss Briggs have places in an officer’s car for the rest of the journey.” “Have you ever been up in the air, Mrs. Gray?” interjected Major Colt. Grace said she had, and related her experience when on a flight with Hippy Wingate, which interested and amused the officers very much. “Never been in an observation balloon?” questioned the major. “No, sir.” “With the general’s permission, I should be glad to have you go up with me, and Miss Briggs too, though she would have to go in another car or else wait until a later date, for the basket is not roomy enough for so many.” “If I am permitted to say so without offense, I believe I should prefer to remain on the ground,” spoke up J. Elfreda. “I have no ambition to soar.” “How about you, Mrs. Gray?” “I should be delighted, sir.” “Done! To-morrow if the weather looks promising; otherwise on the following day, if that is agreeable.” Grace said it was. “I warn you, though,” she added, “that you will be taking desperate chances if I go with you.” “How so?” “Mrs. Gray means that something always happens when she is along,” Elfreda informed them. “Nothing very serious can interfere with us now,” soothed the major. “There are no Boche airplanes to shoot us down, no enemy artillery to shoot off our cables, and, being attached to trucks, we shall move along slowly and steadily behind the army, with a wonderful view spread out before us.” “I know I shall enjoy it until--” “Until what?” demanded the general. “Until the cable breaks,” returned “Captain” Grace with a twinkle in her eyes. “I will let you hear from me early in the morning, Mrs. Gray.” “And I will have a car to take you to the balloons or on toward the front,” added the general. “Then that is settled.” “You spoke of spies a few moments ago,” spoke up Captain Boucher inquiringly. “I was wondering if you had anything in mind?” “Likewise, I was wondering if you were having any spy scares?” answered Grace. Captain Boucher reflected briefly. “We are,” he said. “I am revealing no military secrets when I say that we are.” “You may speak frankly before Mrs. Gray, Captain,” interjected the general. “She is something of an investigator herself, and if ever you get in a pickle call on her to assist you.” “And make a mess of the case,” finished “Captain” Grace. “Pardon me.” “Military information of a vital nature is percolating to the enemy. Of course an army always has and always will have traitors in it, enemy subjects, I mean, but we thought we had stopped all the leaks. It appears that we haven’t.” “It is an impossible task, Captain,” observed Grace.
