"Let us go into the long gallery overhead and dance--dance--dance! My feet are fairly aching for some exercise. Come thou and dance with me."

Kate's word was almost always law to Cherry, though she thought it a dreary place to select just at this hour of approaching darkness. Still, there would be a little light glimmering in through that long row of windows, and with Kate who would be afraid?

The key was in the door. The polished boards of the long ballroom lay gleaming with ghostly shimmer in the fading light. The pictures on the walls seemed to stare at the two intruders with cold displeasure. Cherry shivered slightly as the chill struck her. It seemed to her as if these stately knights and dames themselves must surely come down from their frames at such an hour as this; and silently disport themselves in this long gallery. She was glad to feel Kate's arm about her as she commenced circling round and round in her light and airy fashion. As the warm blood began tingling in their veins the pace grew faster and faster, and Cherry's chilliness and fear alike left her. Up and down, round and round, flew the light girlish feet. The exercise was delightful to both after the inaction of two long days. Up and down, round and round, as though they would never tire; and as they danced the twilight changed to night, and only glimmering moonbeams fell within the row of windows, lighted the long gallery, and fell upon the flickering figures of the two girls.

But their eyes had grown used to the darkness, and they heeded it not. Cherry's thoughts had flown off to Cuthbert, Kate's to Culverhouse. The rapid exercise stimulated thought, and both hearts beat high with the glowing hope of youth. When at last they paused, laughing and breathless, at the upper end of the long room, their eyes were shining brightly, there was a vivid colour in their checks. They only wished to gather breath and then on again.

"It is hot--it is stifling!" cried Kate, as she threw back her tumbled hair. "I must have air--air! I will open this window; we can look out such a way from it. O Cherry, think--this big window looks straight out towards London! Ah, why are not our eyes strong enough to see our loved ones there!"

Cherry laughed and blushed in the darkness, and Kate's strong hand undid the bolt and latch and flung the great casement wide. The cool night air rushed in, and both girls, heated with exercise, were glad to rest their elbows on the stone mullion and lean out into the breezy night.

"It is delicious!" cried Kate; "it is the elixir of life!"

Then the girls were silent for a few moments, till they both started at the same sound.

"That was a gun!" cried Kate suddenly, leaning further out of the window. "Listen, Cherry! There again--another shot! That can only mean one thing!"

"What thing?" asked Cherry, growing suddenly pale with excitement and fear.
