When this book was first released 12 - 15 years ago, it put everything in perspective, especially why the case to which Horace refers time and again over the years was so important to him and his future in the law. I've just reread a couple of the Rumpole tales and had a good chortle over much of their content, but will concentrate solely on this, The Penge Bungalow Murders, because it's arguably the most important of all (well, certainly to the man we see nowadays as a character who looks remarkably like a roly-poly Leo McKern, the Australian actor who made Rumpole his own.)
It's the case of a young man, Simon Jerold, accused of murdering his father and another man not long after the end of WW2, when they teased him about never going to war (an utterly specious point, as he was too young). There is a serious side to it, as there must always be in the story of a murder investigation, but the writing of John Mortimer - himself a barrister, so therefore familiar with the world in which his (anti?) hero lives and works - is humorous and frequently tongue-in-cheek.
Even as I say that, and no matter how well written the stories, I must admit the scriptwriters of the television series, Rumpole Of The Bailey, and the performances of McKern, are at least a match for the originator, but it still remains a joy to read the greater detail in the books.
Back in the day, the old boy's network that operated so greatly by inference or unwritten rule - "It's just not done, my boy..." - meant much of what went on in courts of law might actually work against the accused. In this case, the leader, or senior barrister, and the judge were of the opinion that time spent cross-examining witnesses was a waste of time. In fact, the judge liked to knock off in good time, especially on Friday nights, to get home to his pig breeding hobby. The junior barrister, the 'white wig', was told specifically, in his leader's unavoidable absence, not to upset either judge or jury by questioning prosecution witnesses. Rumpole did, and by so doing saved the life of the accused man he represented.
I doubt anyone who appreciates the very subtlety and nuance of British humour will fail to enjoy this or others in the Rumpole series of books.
I feel I must offer a little spoiler about one of the deliciously humorous passages from the book. Hilda, who will become She Who Must Be Obeyed has her eyes set on Rumpole. She convinces daddy to take him on as junior for the case. She and the young Rumpole are in a cafe when he opens his wallet and out fall three 'rubber johnnies,' bought a few nights earlier for an assignation with another lass that never eventuated. Hilda sees them and is far from shocked. She says something along the lines of, "Oh we must never use them before we are married." Sharing them with her was not something that had ever actually entered the young barrister's mind, so he agreed. By such divergence of meaning did they become engaged.
