This is a short book, and indeed later editions added some short stories to bring the book up to a respectable size. The story is also unusual for this author, for much of the action takes place on the lower floors of a doctor's house in nineteenth century London. The edition used was one of the worst-printed books your reviewer has ever seen, yet with diligence the story has been extracted from it and is here presented. The doctor had for some years been obsessed with an idea that he could make an elixir of eternal life, and at some point in the recent past he had started to neglect his patients, so that he had very few new patients, so there was not much money in the house, and times were hard. The most amusing character in the book is Bob, the "boots" boy, and it is he who at almost the last chapter rediscovers the Bag of Diamonds, that had somehow got lost in almost the first. There are villains, heroes, heroines--and Bob with his antics--in this book, and you will enjoy it. For the whole middle part of the book the people in it are blundering about, none of them ever quite sure what was going on. You, as the reader, may well have a better idea than they do, but be prepared to be wrong in your surmises. Makes a good audiobook. George Manville Fenn lived from 1831 to 1909, and was a prolific writer of boys' adventure stories. He also wrote serialised books for the various boys' periodicals. The feature that is common to most of his books is the method of sustained suspense that he employed. He wrote, in explaining this, that he relied upon the human desire to unravel a mystery, to retain his readers' attention. He was able to retain their interest right up to the very last page, by building up mysterious and dire situations one upon the other. You are constantly left asking, "How does he get out of this one?" It is just this aspect that makes transcribing his books to e-texts such fun. George Manville Fenn, English writer of juvenile stories, was born in London January 3, 1831. He was educated at private schools, then attended Battersea Training College for Teachers from 1851 to 1854. He was Master of a small school in Lincolnshire for a time, then became a printer and published a small magazine of poetry, "Modern Metre," in 1862. Two years later he was part owner of the Hertfordshire and Essex Observer, another unsuccessful venture. He then began writing for various periodicals, such as Chamber's Journal and All the Year Round, and was editor of Cassell's Magazine in 1870, and of Once a Week from 1873 to 1879. He soon began to pour out a flood of books for boys, as well as a few novels, many of which were reprinted in America, and before his death he had published between 175 and 200. He was married in 1855 to Susanna Leake, and by her had two sons and six daughters. He died August 26, 1909. A PDF of scans and an HTML version of this book are provided. We also provide a plain TEXT version and full instructions for using this to make your own audiobook. To find these click on the PDF, HTML or TXT links on the left. These transcriptions of books by various nineteenth century authors of instructive books for teenagers, were made during the period 1997 to the present day by Athelstane e-Books. Most of the books are concerned with the sea, but in any case all will give a good idea of life in the nineteenth century, and sometimes earlier than that. This of course includes attitudes prevalent at the time, but frowned upon nowadays. We used a Plustek OpticBook 3600 scanner to scan the pages. We then made a pdf which we used to assist with editing the OCRed text. To make a text version we used ABBYY Finereader 8 to produce a first draft of the text, and Athelstane software to find misreads and improve the text. We proof-read the chapters, and then made a CD with the book read aloud by either Fonix ISpeak or TextAloud MP3. The last step enables us to hear and correct most of the errors that may have been missed by the other steps, as well as entertaining us during the work of transcription. The resulting text can be read either here at the Internet Archive or at www.athelstane.co.uk
