Next, The Sign of Four presents Holmess famous seven percent solution and the strange puzzle of Mary Morstan in the quintessential locked-room mystery. Also included are Holmess feats of extraordinary detection in such famous cases as the chilling The Adventure of the Speckled Band, the baffling riddle of The Musgrave Ritual and the ingeniously plotted The Five Orange Pips.
