Carol Higgins Clark

Carol Higgins Clark is an American mystery novelist and the daughter of bestselling suspense writer Mary Higgins Clark. She is a novelist in her own right, best known for the Regan Reilly series, following a private investigator navigating cases with a wry, comic touch distinct from her mother's more straightforward suspense style.

Separately from her solo work, Higgins Clark regularly co-wrote a run of light holiday-themed suspense novels with her mother, mixing seasonal warmth with mystery-plot mechanics. In this catalogue she is credited specifically on those co-authored holiday novels, alongside Mary Higgins Clark, and on further Alvirah and Willy entries continuing that collaboration -- distinct from her own independently-authored Regan Reilly series, which is not the subject of this credit.
