— Holmes to Bell
After Detective Bell finds Chantal beaten and unconscious in her apartment, Captain Gregson and Holmes meet him at the hospital. Saying that she has various injuries including a skull fracture, she's being kept sedated and treated for inter cranial bleeding. Having examined Chantal's apartment, Holmes reports her attacker broke in through a window and urinated on her bed. Given the problems that Chantal's ex-husband Roy Booker has been giving Bell of late, he's convinced that Booker is responsible for the assault. After Gregson takes Bell aside to calm him down, Holmes tells Bell that he well understands his need for vengeance and that he'll investigate while Bell tends to Chantal.
