He was up the tree like a cat. He went cautiously along a branch, until he could reach the roof of the shed with his toes. He dropped down on the roof, and Lexy saw him disappear into her room. She went to the back door. In a minute she heard the key turn inside, and the door opened.

“Thank you ever so much, Joe!” she whispered.

But he paid no attention to her. He stood still, drawing deep breaths of the night air.

“Them roses!” he said. “The smell of ’em made me kind of sick, like. Throw ’em out, miss! Don’t go to sleep with them roses in the room!”

Lexy did not answer for a time.

“I’ll see you to-morrow, Joe,” she said. “I’ll pay you for the taxi, and have a talk with you. And thank you, Joe, ever so much!”

He touched his cap, murmured “Good night,” and off he went.

Lexy went in, locked the kitchen door behind her, and stood there, leaning against it, half dazed by the great light that was coming into her mind. She was beginning to understand! The roses—the roses with their strange and powerful fragrance! Her hysterical outburst after her tea at Dr. Quelton’s house! She was beginning to understand, not the details, but the one tremendous thing that mattered.

“He did it,” she said to herself. “He made all this happen. I didn’t just break down. I haven’t been weak and hysterical. He made it all happen!”

For a time her relief was an ecstasy. She could trust herself again. She was so happy in that knowledge that she could have shouted aloud, to waken Mrs. Royce and Captain Grey, and tell them. The monstrous burden was lifted, she was free, she was her old sturdy, trustworthy self again.
