It’s summertime, and Cassie Hall, concierge at the luxurious Parkstone Apartments, is readying the facility’s rooftop pool for opening day. The beautiful red-and-white striped cabana will look fabulous next to the blue water, she notes. The first group to use the pool is the Parkstone swim club, headed by ebullient resident Dot Olive. However, a couple days later when Cassie arrives to check on the group, she finds the pool area empty except for Dot Olive’s dead body underneath the tipped over cabana. Not an auspicious way to start the summer. Another dead body in an ever-lengthening list of corpses that have been accumulating at the Parkstone, much to Cassie’s chagrin and that of her fiancé, Detective Eric Peters, who now apparently has another murder on his plate. No sooner has the body been discovered but Cassie is out sleuthing, trying to determine which of the Parkstone’s rich residents could have offed the effervescent Mrs. Olive. Motives and suspects quickly pile up, and although Eric chastises her about sticking her nose in police business, Cassie just can’t seem to leave the sleuthing to her fiance. That is, until the club room catches fire and a threatening message is left for Cassie in the rubble. Will this scare her into backing off? Not likely. Cassie is determined to find out who killed this Cabana Corpse before summer is over!
