Finding the 3rd volume of The Family Mashber

In the dairies Sholem describes how he and Walter Benjamin were reading a book by Agnon. They were both so taken by the book that Walter exclaimed – “If we have this, why do we need Tanach?” My sentiment exactly about The Family Mashber. Could there be a more important project for our culture than finding the third volume of this book? This book is the most significant spiritual undertaking and statement in the last 100 years (or more).
