?â Sarah asks, speaking more firmly than Iâve ever heard her before. Especially to a teacher.
Now is especially when I want to know. Now, with Zach in the morgue.
âI understand that youâre all upset, but for some people understanding the processes involved can help with grief,â Yayeko says, and I find myself nodding. I am desperate to understand. âWe are all of us subject to the same laws of nature.â
âAnd of God,â Sarah says.
âThe first thing that happens after death,â Yayeko says, âis that blood and oxygen stop flowing through the body. Gravity causes the bodyâs blood to drain from capillaries in the upper parts and to pool in the lower blood vessels. So that parts of the body seem paleâthose upper surfacesâand parts seem dark.â
âWhat if youâre already pale?â Tayshawn wants to know. The class laughs but Iâm not sure he meant to be funny.
âPale is a relative term, Tayshawn,â Yayeko says. âThe lower parts of your body become darker than the upper parts.â
âWhat do you mean upper part, then?â he continues. âLike your head?â
âIt depends on how the body is positioned. If itâs lying supineâon its backâthen the blood pools there. In the heels and calves and buttocks, the back, the back of the neck, the head. The face will be pale.â
Tayshawn nods to show he understands now. I wonder how they found Zach. Which parts of him were pale, which dark?
âNext, the cells cease aerobic respiration so they canât maintain normal muscle biochemistry. Which means what?â
Only two hands go up. Mine and Lucy OâHaraâs.
âLucy?â
âThey stop making energy.â
âOut of what?â
âGlucose,â Lucy says. âOxygen.â
âYes.â Yayeko continues, âAnd when that stops, calcium ions leak into muscle cells, preventing muscle relaxation, which causes rigor mortis.â
âWhen the body goes all hard?â Tayshawn asks. There are more giggles, but he ignores them.
âYes,â Yayeko says. âThe cells begin to die and canât fight off the bacteria, which causes the body to decompose and the muscles to become soft again. As soon as the body dies, flies are attracted to it. They start to lay eggs in open wounds and orifices. The eggs turn into maggotsââ
âNo,â Sarah says, holding her hand over her mouth and running from the room. Two girls get up and follow her. Iâm also imagining maggots eating Zach. Maggots in his eyes, maggots between his toes, maggots all over him. Wriggling, feeding, tearing into his body. I have to concentrate to keep from joining the other girls in the bathroom.
On the way out of class Brandon hisses at me. âYouâre not normal,â he says.
Tell me something I donât know.
AFTER
âI bet you killed him,â Brandon says on the way out of biology. âYou probably got your dad to make him disappear.â
âI heard it was you,â I tell him. âThat you read somewhere if you kill and eat the brains of people who are better than you then you get to be like them.â
âThat makes you safe,â Brandon says. âAnd everyone else in this school.â
I laugh and almost tell him touché. He walks away. I follow. âHow come youâre always hissing at me on the way in and out of class?â
âAre you kidding? I canât have anyone see me voluntarily talking to a murdering freak like you. I wish youâd go back to wearing that mask. That way none of us has to see your freaky face.â
âShut up, Brandon, or Iâll have my dad take care of you.â Briefly I imagine what it would be like to have such a dad. Ready at a moment to kill all my enemies.
Brandonâs eyes flick at me as if heâs trying to assess whether what I said could be true, but doesnât want to
