Mise-an-dhui!” muttered Marsali, regarding her warily. Fiona had backed against the far wall. Donald appeared in search of his twin, and the two went into a conference. Presently they came out of it and presented a solid front to Kelpie, sturdy legs planted wide.

“That is no proof you are a witch,” announced Donald. “Mother and Wee Mairi can tell us apart, and they are no witches, only Mother is knowing us too well and Mairi has Second Sight.”

Kelpie yielded to temptation, made a horrible grimace, and began weaving mysterious signs in the air with her fingers. Fiona screeched, and Marsali turned pale. The twins stood their ground, grinning, belligerent, deeply interested—and just faintly worried.
