Present in this omnibus edition, are four unabridged novels of Baker Streets most famous resident – Sherlock Holmes and his confidant and aide, Dr. Watson. The saga of their adventures begin right from the time they are first introduced to each other by a certain "young stamford" to share rooms in Baker Street, where Watson chronicled their first adventure 'A Study in Scarlet'. 'The Hound of Baskervilles' is perhaps the most popular of his long stories, followed by 'The Sign of the Four' and 'The Valley of Fear'.
