I said, "Do you know what that's a key to?"
He said, "It's a key to a padlock. I have an idea that perhaps it fits the padlock on that locker in the house-boat—the one that was always locked."
Jiminy, I never thought of that until just then when he spoke about it. It made me feel awfully queer. Anyhow, I guessed right off that he was right, because probably it fell out of Lieutenant Donnelle's pocket along with the change that he spilled all over the deck. There was a kind of a lump in my throat now.
I said, "Skinny gave you the money so we ought to believe him when he says he just put the key in another pocket and forgot about it."
"Why, surely," he said, "I'm not suspecting him of anything. Neither is anyone else. The only thing that puzzles me is, how the key happened to be on the deck where he found it. We swabbed the decks so thoroughly before leaving Bridgeboro. One of our boys might have dropped some change and never known it But how did the key happen to be there? We know how it happened in Alfred's pocket, but how did it happen on the deck? We scouts claim to be observant, and yet that key was right on the deck from Bridgeboro all the way down to St. George. That's the queer thing."
Oh, boy, didn't I feel guilty. Especially I felt guilty because Mr. Ellsworth was so nice and pleasant about it. Because all the while I knew where that key came from, and it seemed just like lying not to tell. Gee, I was kind of sorry now that I promised Lieutenant Donnelle that I would never tell about him coming there. I couldn't say anything, so I just kept still.
All the while Mr. Ellsworth kept looking at the key and thinking and humming a tune to himself. Pretty soon he said, "You don't happen to know where Alfred went when he disappeared, do you, Roy?"
I said, "No, I don't; all I know is I couldn't find him."
"He was gone for four or five hours," he said, very slow, as if he was sort of thinking.
I guess I felt just about the same as Skinny did now. Anyway, I was all shaky and it was hard for me to get started saying anything.
