Youth workers Bill Nash and Jim Boyle are house-hunters, not so much for a house as for a concerned family willing to house and feed troubled youngsters temporarily.

25. But after our parents' death, almost no books were permitted.

26. Was it to save electricity, or because books could give “ideas” that would make us too big for our boots?
