In my introduction to the Complete Sherlock Holmes e-book (available for free – http://tinyurl.com/c9hp4ww), I seem to have inadvertently upped the number of novels in the Conan Doyle canon from four to five. One of the joys of e-books is that, unlike with print versions, such glitches can be easily fixed. Yet I knew very well there were four novels – A Study in Scarlet, The Sign of Four, The Hound of Baskervilles, The Valley of Fear – and I can only assume I was so taken in by reading Anthony Horowitz’s House of Silk, I added it to the tally. House of Silk, like Dead Man’s Land, has the blessing of the Conan Doyle Estate, although unlike DML it is written in the style of ACD. Most Holmes ‘continuation’ novels read like a pale imitation of the original, or are so reverential they end up wooden and stilted. Not House of Silk – Horowitz nails the classic characters and doesn’t forget to add a rip-roaring plot. Highly recommended and best read by gaslight.
