"It's a good job for me the place is empty," said Gracie. "I had to get into Mr. Boyd's house somehow, you know, even if I had to climb the wall at the back, the way the murderer and the newspaper man did. As I was looking at the houses I saw these steps, and when nobody was in the Square I crept down. It was all a job to push the door open, but I did, and there I was, without anybody seeing me. Then I tried to get into the backyard, but couldn't. I knew there was only a wall between me and the next house, and I thought of the way prisoners make their escape from prison. They made holes in walls--why couldn't I? I found a bit of old iron in the cellar here, and I poked at the bricks with it till I came across one that was looser than the others. It didn't take me long to push it through, and when I got that out the rest was easy. That's the way of it, Dick."

"You were in the dark all the time."

"That didn't matter. I've got cat's eyes."

"You're a clever girl."

"Thank you, Dick. When you say anything like that to me I feel warm all over."

"What made you so anxious to get into Mr. Boyd's house? Surely you did not expect to find your father there?"

"I don't know what I didn't expect. I thought I might find a bit of paper with his writing on it that'd tell me where to look for him. I told you about my dream the night before last, and how I promised father I'd catch the murderer. I dreamt of him again last night. 'Don't forget your promise,' he said. 'Look for me in Catchpole Square.' 'You ain't dead, are you, father?' I asked. 'No,' he said, 'look for me in Catchpole Square, and catch the murderer.' It's a large order, ain't it, Dick?"

There was nothing humorous in the question; her voice was perfectly passionless, but Dick had a clear sense of the absorbing earnestness and the pitiful pathos which lay beneath, unexpressed though they were in tone or gesture.

"Poor little Gracie!" he said. "The body of a mouse and the heart of a lion."

"I am small, ain't I? But I shall grow. Did I do right, Dick, in coming to tell you about the hole? Don't say you're mad with me."
