In the seriesEdit
In Grave Peril, Kyle and his sister Kelly come to Harry Dresden's apartment bearing an invitation to Bianca St. Claire's ball. He states he is an ordained herald of the court, having licence to carry messages back and forth and to safe passage, under the Unseelie Accords. He is generally more polite than his sister.
Later, Kyle and Kelly use Lydia to trap Harry Dresden, who fights with Kyle. When Kelly charges, Dresden blasts her, he misses and the wall sets aflame. Kelly straddles Dresden and drops of her spittle fall into his mouth, he forgets to fight. The wall collapses, and sunlight enters, burning Kelly's face. Kyle threatens retribution to Dresden.
