The twelve mysteries gathered in this first collection of Sherlock Holmes and Dr Watson's adventures reveal the brilliant consulting detective at the height of his powers. Problems involving a man with a twisted lip, a fabulous blue carbuncle and five orange pips tax Sherlock Holmes' intellect alongside some of his most famous cases, including A Scandal in Bohemia and The Red-Headed League.
