"Marco! Marco! Here I am! Who locked you in? How can I get the door open?"
Marco was close against the door inside. It was The Rat! It was The Rat! And he would be in the street again in a few minutes. "Call a policeman!" he shouted through the keyhole. "The people locked me in on purpose and took away the keys."
Then the group of lookers-on began to get excited and press against the area railings and ask questions. They could not understand what had happened to cause the boy with the crutches to look as if he were crazy with terror and relief at the same time.
And the little boy ran delightedly to fetch a policeman, and found one in the next street, and, with some difficulty, persuaded him that it was his business to come and get a door open in an empty house where a boy who was a street singer had got locked up in a cellar.

"IT IS A VERY BAD SIGN"
The policeman was not so much excited as out of temper. He did not know what Marco knew or what The Rat knew. Some common lad had got himself locked up in a house, and some one would have to go to the landlord and get a key from him. He had no intention of laying himself open to the law by breaking into a private house with his truncheon, as The Rat expected him to do.
"He got himself in through some of his larks, and he'll have to wait till he's got out without smashing locks," he growled, shaking the area door. "How did you get in there?" he shouted.
It was not easy for Marco to explain through a keyhole that he had come in to help a lady who had met with an accident. The policeman thought this mere boy's talk. As to the rest of the story, Marco knew that it could not be related at all without saying things which could not be explained to any one but his father. He quickly made up his mind that he must let it be believed that he had been locked in by some queer accident. It must be supposed that the people had not remembered, in their haste, that he had not yet left the house.
