Having firmly established the characters of Sherlock Holmes and Dr Watson in the novels A Study in Scarlet and The Sign of the Four, Sir Arthur Conan Doyle was retained by The Strand Magazine to contribute a series of twelve short stories, which began with 'A Scandal in Bohemia' in 1891 and were published monthly for the next year. The stories, in which the master sleuth receives a stream of clients presenting him with baffling and bizarre mysteries in his consulting room at 221B Baker Street, were instantly popular and by the time of the publication of the final story, 'The Copper Beeches', they had become the mainstay of the magazine. They included such classic tales as 'The Five Orange Pips' and 'The Adventure of the Speckled Band', and were gathered together in a collection known as The Adventures of Sherlock Holmes, representing some of the finest detective stories ever written.

'Doctor Watson, Mr Sherlock Holmes' - The most famous introduction in the history of crime fiction takes place in Sir Arthur Conan Doyle's A Study in Scarlet, bringing together Sherlock Holmes, the master of science detection, and John H. Watson, the great detective's faithful chronicler. This novel not only establishes the magic of the Holmes myth but also provides the reader with a dramatic adventure yarn which ranges from the foggy, gas-lit streets of London to the burning plains of Utah. The Sign of the Four, the second Holmes novel, presents the detective with one of his greatest challenges. The theft of the Agna treasure in India forms a catalyst for treachery, deceit and murder. With these two classic novels, A Study in Scarlet and The Sign of the Four, you have the brilliant foundation of the Sherlock Holmes canon. Reading pleasure rarely comes any finer.

HarperCollins is proud to present its new range of best-loved, essential classics. 'They all agreed that it was a huge creature, luminous, ghastly and spectral.' Originally serialised in The Strand Magazine, Conan Doyle's The Hound of the Baskervilles follows the infamous Sherlock Holmes and Dr Watson as they investigate the mysterious death of Sir Charles Baskerville, whose dead body is found on the misty and desolate Devon moors. The locals blame his death on the legend of the fearsome phantom hound that they claim has haunted the Baskerville family for generations. When the heir to the Baskerville fortune, Sir Henry, also comes under threat Holmes' detective skills are put to the test as he battles to discover the truth behind the legend and to solve one of the most macabre mysteries of his career.

The Hound of the Baskervilles is the classic detective chiller. It features the world's greatest detective, Sherlock Holmes, in his most challenging case. The Baskerville family is haunted by a phantom beast "with blazing eyes and dripping jaws" which roams the mist-enshrouded moors around the isolated Baskerville Hall on Dartmoor. Now the hound seems to be stalking young Sir Henry, the new master of the Baskerville estate. Is this devilish spectre the manifestation of the family curse? Or is Sir Henry the victim of a vile and scheming murderer? Only Sherlock Holmes can solve this devilish affair. The Valley of Fear is a dark, powerful tale, which provides the great detective with a most perplexing case and opens with a vile murder: "Lying across his chest was a most curious weapon, a shotgun with the barrel sawn off in front of the triggers. It was clear that it had been fired at close range, and that he had received the whole charge in the face, blowing his head almost to pieces". Sherlock Holmes' arch enemy, the criminal genius Professor Moriarty, is back! But the solution to the riddle, found after many surprising twists and high dramas, lies far away, half across the world in a location known as 'The Valley of Fear'. This is Conan Doyle's last Holmes novel and in the opinion of many of his fans, it is the best!

' ... once again Mr Sherlock Holmes is free to devote his life to examining those interesting little problems which the complex life of London so plentifully presents.'. Evil masterminds beware! Sherlock Holmes is back! Ten years after his supposed death in the swirling torrent of the Reichenbach Falls locked in the arms of his arch enemy Professor Moriarty, Arthur Conan Doyle agreed to pen further adventures featuring his brilliant detective. In the first story, 'The Empty House', Holmes returns to Baker Street and his good friend Watson, explaining how he escaped from his watery grave. In creating this collection of tales, Doyle had lost none of cunning or panache, providing Holmes with a sparkling set of mysteries to solve and a challenging set of adversaries to defeat. The potent mixture includes murder, abduction, baffling cryptograms and robbery. We are also introduced to the one of the cruellest villains in the Holmes canon, the despicable Charles Augustus Milverton. As before, Watson is the superb narrator and the magic remains unchanged and undimmed.
