The topic of this book focuses on an area that is doubly challenging. The ‘Q’ element throws up the perennial questions of the existence of this document and more importantly for this study the extent of its putative text. The ‘parables’ element presents the large issue of what is a parable and what is not—basically this is the definitional question. Roth tackles both these issues head-on with verve and originality. The result is a beautifully crafted and richly instructive study. This is a book from which much will be learnt—even by those who do not share all its pre-suppositions concerning Q or the definition and ranges of parables.
