also the chief characteristics of their disorders. I found myself reviewing the data as I flew.
    Schizoid personality disorder types,
as they are currently called, tend to be introverted and indifferent to social relationships. This freak is a classic loner. He tends to have no close friends or close relationships, except possibly family. He exhibits an inability to show affection in acceptable ways. He usually chooses solitary activities for his free time. He has little or no interest in sex.
    Narcissists
are different. They exhibit little or no concern for anyone but themselves, though they sometimes pretend to care about others. True narcissists can’t empathize. They have an inflated sense of self, can become highly unstable if criticized, and feel they are entitled to special treatment. They are preoccupied with grandiose feelings of success, power, beauty, and love.
    Avoidant personality disorder types
usually won’t get involved with other people unless they’re completely sure of acceptance. These types avoid jobs and embarrass easily. They’re considered “sneaky dangerous.”
    Sadistic personality disorder types
are ultimate in badness, as destructive individuals go. They habitually use violence and cruelty to establish control. They enjoy inflicting physical and psychological pain. They like to tell lies, simply for the purpose of inflicting pain. They are obsessed with involving violence, torture, and especially the death of others.
    As I said, all of this ran through my mind as I sat in my airplane seat high over the Atlantic. What interested me mostly, though, was the conclusion I’d reached about Mr. Smith, and which I had recently shared with Kyle Craig at Quantico.
    At different times during the long and complex investigation, Mr. Smith
had fit all four of these classic murderer types
. He would seem to fit one personality disorder type almost perfectly — then change into another — back and forth at whim. He might even be a fifth type of psychopathic killer, a whole new breed of disorder type.
    Perhaps the tabloids were right about Mr. Smith, and he
was
an alien. He wasn’t like any other human. I knew that.
He had murdered Isabella
.
    This was really why I couldn’t sleep on the flight to Paris. It was why I could never sleep anymore.

Chapter 94

    W HO COULD ever begin to forget the cold blooded murder of a loved one? I couldn’t. Nothing has diminished its vividness or unreality in four years. It goes like this, exactly the way I told it to the Cambridge police.
    It is around two in the morning, and I use my key to open the front door of our two-bedroom apartment on Inman Street in Cambridge. Suddenly, I stop. I have the sense that something is wrong in the apartment.
    Details inside are particularly memorable. I will never forget any of it. A poster in our foyer:
Language is more than speech
. Isabella is a closet linguist, a lover of words and word games. So am I. It’s an important connection between us.
    A favorite Noguchi rice paper lamp of Isabella’s.
    Her treasured paperbacks from home, most of them Folio. White uniformed spines with black lettering, so perfect and neat.
    I’d had a few glasses of wine at Jillian’s with some other medical students, recent graduates like myself. We were letting off steam after too many days and nights and weeks and years in the Harvard pressure cooker. We were comparing notes about the hospitals each of us would be working at in the fall. We were promising to stay in touch, knowing that we probably wouldn’t.
    The group included three of my best friends through medical school. Maria Jane Ruocco, who would be working at Children’s Hospital in Boston; Chris Sharp, who was soon off to Beth Israel; Michael Fescoe, who had landed a prize internship at NYU. I had been fortunate, too. I was headed to Massachusetts General, one of the best teaching hospitals in the world. My future was assured.
    I was high from the wine, but not close to being drunk, when I got home. I was in a good mood, unusually carefree. Odd, guilty detail — I was horny for Isabella.
Free
. I remember singing “With or Without You” on the way back in my car, a ten-year-old Volvo befitting my economic status as a med student.
    I vividly remember standing in the foyer, seconds after I flicked on the hall lights. Isabella’s Coach purse is on the floor. The contents are scattered about in a three-or four-foot radius. Very, very strange.
