It was a dark and stormy night, but that was the least of Theodosia Browning's troubles. As she approaches St. Philips Graveyard, Theodosia witnesses a brutal murder and sees a dark-hooded figure slip away into the fog. As she is alerting police, Theodosia recognises the victim - it is the daughter of her friend, Lois, who owns the Antiquarian Bookshop next door to her own Indigo Tea Shop. Even though this appears to be the work of a serial killer who is stalking the back alleys of Charleston, Lois begs Theodosia for help. Against the advice of her boyfriend, Detective Pete Riley, amateur-sleuth Theodosia launches her own shadow investigation.
