What is there to say about ANY of Mortimer's "Rumpole books"?
How can anyone not possibly enjoy reading of Horace Rumpole's adventures and misadventures? Can anyone find fault with a writer who does justice to whatever educational system laid the foundations for his excellent use of the English language (I am a non-native speaker). Excellent use of appropriate vocabulary helps the reader to experience Rumpole rather than just read about his iconoclastic capers.
But let the reader be warned! Reading any one of the Rumpole books is to flirt with an incurable addiction! Even when one acquires and reads the complete series there follow many periods of re-reading. And equally enjoyable re-reading it is too - I should know, I started reading Rumpole almost three decades ago and still do so from time to time :)
