An Auden & O’Callaghan Mystery pairs two investigators whose professional partnership carries personal undertones. Each title follows the “A Friend in the…” pattern, beginning with A Friend in the Dark (2020) and continuing through A Friend in the Fire and A Friend in the Glass.
Ashe builds the series slowly, letting the relationship between Auden and O’Callaghan develop across cases that test both their detective skills and their trust in each other.
