As Holmes and the BSI begin their investigations into a gruesome murder, all at once the detectives find themselves in danger. When a personal associate of the master detective disappears, Ozzie, Wiggins, and the gang know that they must uncover the truth — and quickly! Yet there is deception within their ranks. Who is a friend? Who is a traitor? Who can they trust?
Join the Baker Street Irregulars as they search to find Watson and the double-crosser before it's too late!
