Skeleton in a Dead Space. Kelly O'Connell Mysteries, #1

Kelly O'Connell never thought real estate was a dangerous profession. But while updating early-twentieth-century Craftsman houses in an older neighborhood in Fort Worth, Texas, she stumbles over a skeleton and begins unraveling an old murder. The police call it a cold case, but Kelly knows she must solve the murder if she is to finish the house and sell it. She and her two young daughters quickly become the target of threats and vandalism, and someone is telling her ex-husband in California what's going on.
Tim Spencer arrives to protect his daughters by taking them to California with him but is soon found shot to death. Then a new client barges into Kelly's life, and she finds herself facing a gun, a deadly killer, and the solution to the mystery of the skeleton and Tim's death.
