Books such as this are frustrating. The phrases covered are easily identifiable by other means, including the internet, while they lack the depth required to make a meaningful contribution to knowledge or history. In some areas they differ from explanations provided elsewhere but, with so few specific references to the original, it's hard to test their integrity and coherence.
The author provides a thematic index which is more helpful than the A to Z layout of the book overall. There are also specific areas dealing with parts of the body, sport, animals, foreign countries and biblical expressions. There are some phrases which I had never come across before - and won't miss - while Tallulah Bankhead's "Pure As the Driven Slush" always raises a laugh.
Reading this volume evoked memories of comedian Rob Wilton and the line "What good are you?" The book barely gets away with a positive answer other than as an introductory volume in the acquisition of useless knowledge. Off the cuff, I'll chance my arm, bite the bullet, jump on the bandwagon and award it three for the benefit who want to keep ten year olds quiet at Christmas or on birthdays.
