Turn of the century sleuth Francesca Cahill finds herself on the trail of a slasher. A madman with a knife has attacked several women on the Lower East side of Manhattan, and the victims' proximity to Francesca's close friends, the Kennedy family, has her especially worried.
Francesca also has to contend with the jealousy of her smoldering fiance Calder Hart, as she resumes her investigative partnership with Calder's brother, police commissioner Rick Bragg.
In the later books of the series, Joyce has fleshed out the secondary characters' relationships and those have become nearly as interesting as Francesca and Calder's steamy courtship. Again, mysteries? Secondary.
