In the London of 1894 and 1895, master detective Sherlock Holmes takes on six baffling cases spanning murder, theft, and mysterious disappearances, from an ill-tempered whaling captain found impaled in his cabin to an entire train that vanishes without a trace. Alongside Dr. Watson, Holmes scours crime scenes, examines witnesses, performs autopsies, and pieces clues together into chains of deduction to name the guilty. But each solution carries a moral weight: once he identifies a culprit, Holmes, and the player, must decide whether to condemn them to justice or grant them mercy.
