Then came learning to mount. When Lilly planted her foot in his joined hands she felt a warm thrill creep up her spine to the back of her neck, as if this contact were a sign of the secret understanding between them.

He counted "One, two, three," and, presto! there she was in the saddle.

The colonel clapped and applauded, and Walter blushed to the roots of his fair hair with delight.

Henceforth he had the game in his hands.

"Who would have thought that jackanapes had so much of the pedagogue in him?" the colonel remarked to Fräulein von Schwertfeger, who nodded silently and drew a deep breath as if something weighed on her mind.

When Lilly dismounted she had learnt how to draw in the reins and slacken them, and to turn to right and left. She had even got as far as a trot round the yard. The colonel said good-humouredly she promised to be the most dashing horsewoman in the army.

One lesson followed another. Either the colonel or Anna was always present, so there was little opportunity for a confidential conversation. Walter did not drop his stiff and obsequious manner, though Lilly longed for a flash of the old devilry that she alone understood.

Then came a day when it happened that both sentinels were absent from duty. The colonel was busy giving directions for the making of a covered riding-way where his gouty limbs would not be exposed to chills, and Fräulein von Schwertfeger was nowhere to be found.

Lilly's heart beat fast as she and her merry friend met, and she gave him her hand with a smile of suppressed triumph. He responded with a sly wink in the direction of the terrace, where her duenna was wont to stand.

"She's nowhere to be seen," whispered Lilly.
