Grime and PunishmentPaperback - 1992
With three kids to raise on her own, Jane Jeffry sometimes needs a hand with the housework. But many of her complaining neighbors believe that the Happy Helper cleaning lady they all share wouldn't know a dustball if she was choking on it. That hardly seems reason enough, however, to do the disreputable domestic in.
So when the charwoman in question is discovered strangled to death with a vacuum cleaner cord, Jane decides to dig up the real dirt--if the tenacious single mom can find any time to spare between her PTA meetings and car-pooling duties. But despite her busy schedule, Jane is determined to tidy up the whole murderous mess--even if it means provoking a killer who may live as close as next door.
