Here's another author with an oddly charted sales record. Dr. Serecold was a dark horse sensation. I question whether anything she has published since has equalled it, though Family Cruise was better entertainment, and Hornet's Nest did better, I believe, in actual number of sales. Now comes People in Cages which has the compactness of Dr. Serecold, whose threads chance to draw together at one point (in this case the London Zoo). But it also has what I felt to be the weakness of that book -- so determined is she to keep her analogy clear, to eliminate extraneous matter, that the results seem two-dimensional, insubstantial, the people lack reality. It's an endlessly fascinating theme -- the cages of greed and avarice and selfishness and public opinion and fear and habit and love and hate, in which humanity is imprisoned. It is, in the last analysis, a trick book, but it affords good reading and sets many wheels revolving. Well done, within limits.
