Facebook

Only Facebook allows you to unlock the game, connect with friends and choose which of them will be your Holmes or Watson.

Use Facebook to send status updates to everyone in your network as you solve each piece of the mystery, and prove yourself as one of the great detectives of our time.

Remember, you must be over 14 years of age to play. When you unlock the game with Facebook, you'll be shown a series of special permissions: you must agree to the permissions for Email and Offline Access; the permissions for Status Updates are optional.

Flash and Silverlight

Only Microsoft Silverlight and Adobe Flash will let you see every detail, so make sure you have the latest versions installed.
