"Sherlock [Jonny Lee Miller] and Joan [Lucy Liu] are looking into the case and start to think it's not really what it appears to be," executive producer Rob Doherty tells TVGuide.com. "It appeared to be a home invasion gone terribly awry, but they're beginning to suspect that the scene was set to look that way. So they certainly have questions for [Marion]."
However, Sherlock will make a startling discovery through the investigation. "As Sherlock and Joan start to get a better sense of Marion, what they find is that her husband had a secret connection to Sherlock and Mycroft [Rhys Ifans]. They realize that her husband is someone who once upon a time was tasked with keeping an eye on Sherlock Holmes."
