" I’ve grown more comfortable working with the dead. With parts of them, really. A few teeth, a vertebra, a piece of carpet that lay underneath a body for awhile. One of my German shepherd’s standard training materials is dirt harvested from sites where decomposing bodies rested. Crack open a Mason jar filled with that dirt, and all I smell is North Carolina woods—musky darkness with a hint of mildewed alder leaves. Solo smells the departed. "
