ROTTEN EGGs (A Basil and Hortense Killingsley Mystery)
ROTTEN EGGs employs the professorial couple, Hortense and Basil Killingsley, who are the amateur sleuths in All Booked Up (Dodd, Mead, 1987; Worldwide Press, 1989, Kindle Ebook 2012). In Rotten EGGs they get embroiled with a crotchety learning-in-retirement group whose gala social events are infested with poisonous potluck snacks. The EGGs, happy to boast their several sorts of intellectual vitality, must face the fact that one of them is rotten when the their indefatigable social director falls prey to hallucinogens in the Bird and Mushroom Hunt picnic salad. Several EGGs have opportunity, means and motive, so finger pointing is rife, but not confined to the retirees, as poison is stuffed into candies and tuna sandwiches prove lethal in other corners of the academy. Are the unauthorized ingredients coming from the biology department, where the refrigerator holds more than beverages and bag lunches? Is the homeopathic EGG responsible? The herbalist? Is the quest for publication—or the cover for plagiarism--at the heart of lethal matters?
