Baker Street Detective

From the game's package:

"You are Sherlock Holmes, the world's greatest detective; and you have just been presented with two new mysteries to solve. In the case of A Wasted Witness, Inspector Lastrade asks you to investigate the mysterious death of the Government's star witness during an extortion trial. In the Scourge of the Executioner, you try to find a link between the murder of a bank president, and a bank robber who wears an executioner's hood.

BAKER STREET DETECTIVE brings you back to 1893 London. You are provided with a map of the city and a directory of people and places that you can visit. Armed with these tools and your own reasoning skills, you must solve each of the two mysteries and then take a quiz to test your knowledge. Careful, your score will be compared to Holmes' own solutions! This program is a must for anyone interested in mysteries or Sherlock Holmes"
