UNFORTUNATELY, KEEFE WAS RIGHT.
Elwin coated the necklace with reveldust—a special spore that
could detect the presence of ogre enzymes—and the second the
powder touched the dark metal, the pendant glowed bright pink.
So did Keefe’s hand.
And parts of Sophie’s chest, neck, and glove.
Elwin even spotted pin-size holes along the pendant’s edge,
housing microscopic colonies of whichever bacteria secreted the
enzyme.
“I thought something was only a tracker if it glowed red,” Dex
argued.
Keefe shook his head. “Red means aromark, which doubles as a
tracker because it’s a homing device for ogre weaponry. Green would
be a basic tracker. Pink is . . . I don’t know—but if it’s there, it can’t be
good.”
He kicked the nearest cot so hard it made everyone wince.
Ro rumpled his hair. “Listen to my little elf boy, sounding all
knowledgeable about microbiology and stuff! I’ve never been so
proud.”
Keefe didn’t bother to respond.
“So what does pink mean?” Magnate Leto asked.
