"Nonsense! Did I, Miss Lucy?"

"Yes, you did a little, Jan," she replied.

"What a stupid you must be!" retorted gallant Jan. "I should say you want doctoring, if your nerves are in that state. You take—"

"Oh, Jan, that will do," laughed Lucy. "I am sure I don't want medicine. You know how I dislike it."

They were standing together within the large window, Jan and Lionel, Lucy sitting close to them. She sat with her head a little bent, scenting her verbena.

"The truth is, Jan, I and Lucy have been watching some intruder who had taken up his station on the lawn, underneath the yew-tree," whispered Lionel. "I suppose Lucy thought he was bursting in upon us."

"Yes, I did really think he was," said Lucy, looking up with a smile.

"Who was it?" asked Jan.

"He did not give us the opportunity of ascertaining," replied Lionel. "I am not quite sure, mind, that I did see him; but Lucy is positive upon the point. I went to the tree, but he had disappeared. It is rather strange why he should be watching."

"He was watching this room attentively," said Lucy, "and I saw him move away when Mr. Verner went on the lawn. I am sure he was a spy of some sort."
