Plot

"No. We're much better than that. We're two people that love each other. We always have been." — Holmes to Watson

In the wake of Michael Rowan's killing, Watson is questioned by FBI Agent Mallick. Watson's alibi is weak as she was at her parent's house, but only her mother was present. Mallick believes Watson killed Rowan as an act of obsession after he invaded The Brownstone and attacked her. Mallick plays Watson a recording of Rowan leaving an internet voicemail for William Bazemore when he was killed in which Rowan says "Joan." Watson asks for a lawyer. Holmes and Watson consult with an attorney who believes she'll have a tough time defending Watson and indicates that Mallick wants Watson imprisoned. In private, they confirm that neither of them did kill Rowan and without the NYPD's help, Holmes says they'll have to cheat in their investigation. Holmes surprises Captain Gregson at his home and asks for help which Gregson can't give as he's being too closely watched.

I wanted him behind bars too.

At the Brownstone, Holmes has Watson review Rowan's autopsy report which he stole from the Morgue. He's blown up a picture of Rowan's corpse significantly. Watson notices that Rowan's orbital bone was fractured meaning he was concussed as he died and, that the wound Watson inflicted on him when he attacked her has been stitched up by a former Vietnam war medic. Holmes has an idea who the medic might be. At a support group meeting, Holmes confronts Denny Mulgrew. In private, Mulgrew admits to helping Rowan but didn't know he was a serial killer. Rowan told him he was stabbed trying to buy drugs. He let Rowan stay at his house overnight but he left in the morning. When he learned of the accusations against Rowan, he kept quiet, fearing imprisonment. Holmes says he'll protect him from the police if he helps him.

Note the wound you inflicted.

Holmes has Watson meet him at Mulgrew's house. He asks her to don a hairnet and surgical mask so she'll leave no DNA traces. He finds some traces of blood splatter and that the floor has been chlorinated. Spraying luminol on the floor, he sees woman's shoe prints that are the same size as Watson's.

I feel ridiculous.

Quotes

Well then it's over, you know. You know, our little family unit. You, me, the Captain, Marcus. We'll never be able to set foot in that precinct ever again.

— Holmes to Watson
