“And now, Adventure, come forth!” commanded Katherine in sepulchral tones.

The side door of the cottage, leading to the garden, now opened as though at Katherine’s orders, and a broad ribbon of light fell across the labyrinth, picking out the snub-nosed Hebe and the sun-dial and one of the box chairs to illuminate. A man’s figure was silhouetted in the doorway, a figure so beautiful that the artist in Judy gasped. He had on running togs which exposed his clean-cut limbs and shapely shoulders. A woman stood beside him and Judy recognized the outline of Madame Misel. The Greek god of a man was strange to her, although there was something familiar about the poise of his head on its column-like neck.

The woman spoke in German in a low clear voice. Judy and Katherine both knew German fairly well and Otoyo had some knowledge of it. They heard Madame Misel say distinctly:

“It is wiser if you wait until midnight for the exercises. Some of these blockheads might be out.”

“Oh, absurd!” answered the man. “There is no one in this whole stupid place with the spirit to be from under cover after ten. I am cramped enough and must run and leap. Stand aside!”

“Misel, himself!” gasped Judy. Where were his crutch and cane and his lame back?

The girls sat as still as the stone Hebe. It was inky black in their corner of the summer-house where they cowered, not afraid at all but ready to knock the chip from the shoulder of Adventure. Judy’s first instinct on recognizing Madame Misel was to make herself known and explain their presence in her garden at such a late hour, but the realization that Misel was the man in running togs, which usually means running, glued her to her bench. What did it all mean?

The door was shut and then Misel began a series of exercises of which any circus actor might have been proud. He began by leaping over the clipped hedge of the labyrinth,—back and forth with most surprising gyrations. It was so dark that it was difficult to follow his every movement, and so rapid were his leaps and bounds that he was now here, now there before eyes could be focussed to take in the impression. Then almost without the girls realizing what had happened, he had cleared the five-foot hedge and was out on the deserted street running like a deer.

“Quick, before he is back!” gasped Judy, and the seekers for sensations were out of the garden and through the little turnstile in not much more time than it had taken the master of the house to leap the hedge.

Without a word they hastened back to the college grounds. As they turned a corner, they ran plump into Misel, who seemed to have let off steam enough to be trotting contentedly home. They need not have feared him. He was much more anxious to escape from them than they were from him. He turned and ran like the wind in the opposite direction.

“Gee, I wish we could have tripped him up!” exclaimed Judy.

“And I might have jiu jitsued him most neatlily,” put in little Otoyo. “I think he is what you might call a traitor-r-r.”

“I was never more excited in my life. What will the girls think when we tell them of what has happened to us?” panted Katherine.

“Do you realize we have run against a tremendous thing?” said Judy soberly. “Almost international importance! I fancy we must keep kind of quiet about it. Of course we will tell Molly and Edwin and the girls, but I have an idea this thing will have to be worked up slowly and cautiously. I bet you it will be a case of secret service men and enemy aliens and what not. Why should Misel have pretended to be lame? Why should they come to live at Wellington? Why—a million whys about the whole matter!”

“One thing:—Misel thought we were college girls on a lark and he will have no fear of our saying we met him or anyone outside the campus at such an hour,” said Katherine wisely.
