There's been a murder in Pinnacle, Texas. The list of people who disliked the victim strongly enough to kill him is a long one, but the local police have focused on just two people: Ivy Greene, the one who discovered the body; and James Williamson, the mechanic who recently returned to his home town.
Ivy has enough on her hands as the single mother of a precocious six-year-old daughter and the owner of her own small business. Adding amateur detective to the list of her daily duties isn't something she really wants to do, but she feels compelled to find justice for the man that even she'd never liked. As Ivy sorts through the clues, she also works to help her daughter understand the true meaning of the words contained within the Lord's Prayer.
