Series 3. Disc 3DVD - 2009
"On Halloween, called to a scene as she's leaving for the evening, Dr. Hobson finds the friend she was on her way to meet dead, with a stake through her heart and garlic in her throat. Though the pathologist is officially removed from the case, Lewis and Hathaway are happy to have a trusted face in their investigation. But when a student turns up murdered the next day--the two are put in the uncomfortable position of conducting a more intrusive investigation into her past to determine what, if any, role she plays in the current case. Though Lewis is hesitant to list her as a suspect, when a third body turns up he is forced to acknowledge that Laura Hobson might know more about these deaths than she is letting on."
