toilet tank, holding him upright.
  Through the semitransparent bands of tape, three separate bullet wounds were visible in 
his chest. There might have been more than three. She didn't care to look for them and 
had no need to know. He appeared to have died instantly, most likely in his sleep, and to 
have been dead before he was brought into the bathroom.
  Grief welled in her, black and cold. Survival meant repressing it at all costs, and 
surviving was the thing that she did best.
  A collar of strapping tape around Paul's neck became a leash that tethered him to a 
hand-towel rack on the wall behind the toilet. The purpose was to prevent his head from 
falling forward onto his chestand to direct his dead gaze toward the shower. His eyelids 
were taped open, and in his right eye was a starburst hemorrhage.
  Shuddering, Chyna looked away from him. Although the intruder had needed to kill Paul 
in his sleep to establish control of the house quickly, here he had been fantasizing that 
the husband was being forced to watch the atrocities committed against the wife.
  This was a classic tableau, a favorite of those sociopaths who took delight in 
performing for their victims. They actually seemed to believe that for a while the 
recently dead could still see, still hear, and were thus capable of admiring the bold 
antics and posing of a tormentor who feared neither man nor God. Textbooks described the 
delusion. In one of her aberrant-psychology classes at UCSF, a speaker from the FBI's 
Behavioral Science Section had given them more graphic descriptions of such scenes than 
any textbooks could provide.
  Firsthand, however, the impact of this brutality was worse than words could convey. 
Almost paralyzing. Chyna's legs felt heavy and stiff. The tingling in her hands was 
incipient numbness.
  Sarah Templeton was in the stall shower, which was separate from the tub. Although the 
glass door was closed-and frosted-Chyna was able to see a faint, vaguely pinkish shape 
huddled on the shower floor.
  On the face of the soffit above the glass door, the killer had printed two words. The 
black letters appeared to have been made with multiple strokes of an eyebrow pencil: 
DIRTY BITCH.
  Chyna had never wanted anything as much as she wanted to be free of the obligation to 
look into this shower stall. Surely Sarah could not be alive.
  Yet if she turned away without being certain that the woman was beyond all help, 
ineradicable guilt would ensure that her own survival would become a kind of walking 
death.
  Besides, she had committed her life to trying to understand this very aspect of human 
cruelty, and no published case study would ever bring her closer to comprehension than 
might the things that she saw here. In this house, on this night, the bleak landscape of 
the sociopathic mind had been externalized.
  Echoing off the tile walls, the sizzle-splash of the falling water sounded like the 
hissing of serpents and the brittle laughter of strange children.
  The water must be cold. Otherwise, steam would,have been seething over the top of the 
shower enclosure.
  Chyna held her breath, gripped the anodized aluminum handle, and opened the stall door.
  Sarah Templeton had been wearing a pale-green teddy and matching panties. Her garments 
were in a sodden ball in one corner of the shower.
  After her husband had been shot, the woman had evidently been hammered unconscious, 
perhaps with the butt of the gun. Then she had been gagged; her cheeks bulged with 
whatever rag had been forced into her mouth. Strips of strapping tape had sealed her 
lips, but in the relentless icy spray, the edges of the tape had begun to peel away from 
her skin.
  With Sarah, the killer had used a knife. She was not alive. Chyna quietly closed the 
stall door. If there was such a thing as mercy, then Sarah Templeton had never regained 
any awareness after being knocked unconscious.
  She remembered the hug that Sarah had given her on the front walk when she had first 
arrived with Laura. Repressing tears, she wished that she herself were dead instead of 
the precious woman in the shower stall. Indeed, she was half dead and less alive by the 
minute, because a piece of her heart died with each of these people.
  Chyna returned to the bedroom. She moved away from the bed but didn't go immediately 
toward the hall door. Instead, she stood in the darkest corner, shaking uncontrollably.
  Her stomach rolled. An acidic burning rose in her chest, and a bitter taste filled the 
back of her mouth. She suppressed an urge to vomit. The killer might hear her retching, 
and then he would come to get her.
  Although she'd met Laura's parents only the previous afternoon, Chyna had known them 
also from her friend's numerous anecdotes and colorful stories of family adventures. She 
should have felt even more grief than she did, but she had only a limited capacity for it 
right now. Later it would hit her harder. Grief thrived in a quiet heart, and right now 
hers thundered with terror and revulsion.
  She was shocked that the killer had done so much damage while she had sat, unknowing, 
at the guest-room window, brooding on the stars and thinking of other nights when she had 
gazed at them from rooftops, backyard trees, and beaches. From what she'd seen, he had 
taken at least ten or fifteen minutes with Paul and Sarah before searching the rest of 
the large house to locate and overpower the remaining occupants.
  Sometimes a man like this got a special thrill from risking interruption, even 
apprehension. Perhaps a half-asleep, bewildered child would be drawn into the 
parents'room by some commotion and then would have to be pursued and dragged down before 
escaping the house. Such possibilities heightened the pleasure that the creep took from 
his activities in the bedroom and the bath.
  This was a pleasure to him. A compulsion, but not one over which he despaired. Fun. His 
recreation. No guilt-therefore, no anguish. Savagery gladdened him.
  Somewhere in the house, he was either at play or resting until he was ready to begin 
the game again.
  As her shakes subsided to shivers, Chyna grew increasingly afraid for Laura. Those two 
muffled cries, minutes ago, had surely come after Sarah was already dead, so Laura must 
have been surprised in her sleep by a man smelling of her mother's blood. As soon as he 
had overpowered and secured her, he had hurried to search the rest of the second floor, 
concerned that another member of the family might have been alerted by her stifled 
screams.
  He might not have returned immediately to Laura. Having found no one in any of the 
other rooms, confident that the house was firmly under his reign, he most likely had gone 
exploring. If the textbooks were correct, he would probably wish to violate every private 
space.
  Pore through the contents of his host's and hostess's closets and desk drawers. Eat 
food from their refrigerator. Read their mail. Perhaps finger and smell the soiled 
clothing in the laundry-room hamper. If he could locate collections 'of family 
photographs, he might even sit in the den for an hour or longer, amusing himself with 
those albums.
  Sooner or later, however, he would return to Laura. Sarah Templeton had been an 
extremely attractive woman, but night visitors like this man were drawn toward youth; 
they fed on innocence. Laura was his meat of choice, as irresistible as birds' eggs
