In contradistinction to the invidious suggestion of the term the ""silver chord"", this is a story of an idealistic relation between mother and son, paralleling the formula Warwick Deeping immortalized in Sorrell and Son. London -- shifting from the poverty striken background of Karl's boyhood, when his Jewish mother supported an invalid husband and three boys, by running an old clothes shop, to the smart set of London's theatrical and literary life -- such is the background. And the story is a glamorous success story, from poor boy to successful dramatist, with a few pitfalls cleverly evaded through the adroit handling of the mother. Not wholly credible -- but what matter? Deeping has his following -- and this is a sure best renter, and will build up healthy sales.
