forced or otherwise. According to the police, that showed she hadnât been killed by someone trying to rob or rape her. I talked to the detectives myself yesterday.â
âWhatâs Stanley say about that?â
âHe claims those facts are equally consistent with a homicide motivated by something other than rape or robbery.â I took a bite of my quiche. âThere was no suicide note.â
âReally?â
âThe police couldnât find one, and they did a thorough search. No note in her apartment, in her office, on her computer, in her email, on her Facebook page, on her body, in her car. Nowhere.â
âIs that significant?â
âStanley thinks so, but the detectives told me that many people kill themselves without leaving a suicide note.â
âSo what about Stanleyâs evidence?â
âThey confirmed that the heel on her left shoe was missing and that Stanley had found the missing heel. Theyâre going to run the prints on the Blistex tube, but they said the results wonât change their conclusion.â
âWhy not?â
âTheir view is that things can fall out of an open purse, especially if she was in the process of climbing over the barrier. If youâre about to kill yourself and a tube of lip balm falls out of your purse, why would you even care?â
âWhatâs Stanley say?â
âIn his scenario, sheâs walking to her car and looking in her purse for her keys when sheâs attacked. The tube falls out during the struggle and rolls under another car.â
Benny shook his head. âI know you say this guy is smart, but does he really think a broken heel and a Blistex tube are proof of murder?â
âHe views them as corroborating evidence.â
âCorroborating what?â
âThat she wasnât depressed or suicidal.â
âAnd whatâs that based on?â
I sighed. âHer face.â
âHer face?â
âYes.â I smiled. âTo quote Stanley, âI can assure you, Ms. Gold, that the orbicularis oris never lies.ââ
âWho?â
âNot who. What. The orbicularis oris is apparently a facial muscle.â
Benny stared at me. âA what?â
âIâm serious. Stanley is the idiot savant of facial muscles.â
âWhat the hell is a facial muscle?â
âNormal people can tell whether someone is happy or sad or angry just by looking at their face. People with Stanleyâs autism problem canât. They canât read other peopleâs emotions and moods. It causes all kinds of problems for them. According to his mom, a few years ago a doctor gave Stanley a chart of facial expressions. Itâs a chart created specifically for people with his problem. It shows a set of six or so basic facial expressions, and each one is labeled. So thereâs Happy and Sad and Angry and Scared. The goal is to help people like Stanley recognize the emotional states of people around them.â
âOkay.â
âThe chart fascinated Stanley. He started doing research and learned all about FACS, which is an acronym for the Facial Action Coding System.â
âWhat the hell is that?â
âFrom what I understand, FACS is a whole field of study. It identifies every muscle in your face and assigns an action code for each possible contraction or relaxation of one or more of those muscles. There are something like two dozen facial muscles and more than a hundred action codes, and hundreds of possible combinations. Thereâs this famous FACS manual. Itâs more than five hundred pages long, and you can apparently use it to identify every possible emotion and mental state. For example, there are certain action codes for a genuine, involuntary smile, and other action codes for a fake one, like when a photographer tells you to smile.â
âWhatâs the purpose of all that?â
âApparently, there are lots of
