Caroline Slade -- in successive books- has presented in graphic human terms various case histories out of the files of social work- but she has done it in such a way that only occasionally is the fact driven home. Mrs. Party's House is an amazingly likable story of a nice little woman, trained for nothing that would support her and her invalid mother -- and precipitated by circumstances into running a ""house"". A very unusually respectable house, to be sure- way ahead of its time -- and she occasionally preened herself on her service to humanity. But chiefly she was busy helping people,- girls who were headed for utter depravity, girls who found in her the one sound core of life. Implicitly, the story is an attack on the hypocrisy of society; occasionally, it gets preachy. But in its fundamentals- in the story telling- it seems to me worth while. Not, perhaps, a book for the conservatives; the plain facts of life inside a whore house are not for juvenile consumption. But there's plenty here to make the reader ponder.
