Right of Redemption - Savannah Martin Mysteries , #18

When Savannah and her best friend Charlotte decide to flip a foreclosed property in nearby Columbia, they talk Savannah's sister Darcy into putting up the money for the renovations, and go to work. But no sooner have they ripped up the carpet and torn out the kitchen cabinets, than the previous owner shows up and invokes his statutory right of redemption. After four years in prison for a crime he says he didn't commit, he's back in town to clear his name, and he wants his house back.
And according to Savannah's legal-eagle brother Dix, there's nothing anyone can do to stop him. Until someone drops him in his tracks, with a murder weapon that has Charlotte's fingerprints all over it. Savannah's husband Rafe has his hands full at the local PD, so the murder investigation falls on another detective, one who doesn't share Savannah's conviction that Charlotte wouldn't hurt a fly. But when Savannah decides to do some investigating of her own, it soon becomes clear that there's more to this flipping fiasco than meets the eye.
