Continuity mistake: When Marcus and Joan are watching Gephardt's video, he says he's taken lives. At this point the play bar is by his fingers. It cuts to Marcus and Joan, and we hear the video continue to play for more than 12 seconds. When it cuts back to the video, the play bar is nearly in the same position, when it should be well past his hands and near his elbow.

Chosen answer: M broke into the brownstone and left a note. Holmes deduced he was staying at a high-class hotel from the soap scent on the note, and gave a picture from a hidden camera to his "irregulars" on the street to stake out hotels. One of them saw him, so Holmes followed him to his next intended victim and knocked him unconscious with a baton.
