"In God's name, what does it mean?" "It means murder..." When Miss Mary Morstan calls on 221B Baker Street, the "utterly inexplicable" story she tells stirs the heart of Dr. John Watson - and rouses his friend Sherlock Holmes from his self-induced lethargy. For who else but London's only unofficial consulting detective could possibly solve the mystery of the disappearing Army officer, the one-legged man, his barefoot accomplice, the missing treasure-chest, and... the "sign of the four"? This atmospheric graphic novel adaptation by Ian Edginton and I.N.J. Culbard - the team behind this series' acclaimed The Hound of the Baskervilles, The Sign of the Four and The Valley of Fear - will keep you guessing.
