The house guest - Eleanor Nilsson

Gunno belongs to a gang that steals from houses. But when he and the other children break into The Big House, Gunno finds that his life begins to change. He is attracted back to the house and, against all the rules of the gang, he goes there again and again until he begins to think of it as his own. But he has a growing sense of urgency while he is there, a feeling that there is something he has to do, something that only he can do. This feeling is connected with Hugh, the mysterious lost boy of the house. It is his fascination with the house, and with Hugh, that finally leads him into great danger.
