The Ghost Orchid Murder — Nancy Jill Thames

It's been eight years since gardening columnist Jillian Bradley helped solve a string of murders in Half Moon Bay. But when a friend and colleague in Scottsdale, Arizona finds a young technical assistant dead on the floor of his private office, Jillian doesn't hesitate to answer his plea for help. After all, a $2 million research grant depends on it. Together with Detective Jack Noble and Jillian's clue-sniffing dog, Teddy, the three set out to track the killer who leaves a porcelain ghost orchid over the wound as the only clue. Even though it means personal sacrifice for Jillian, she is determined to uncover the truth. A faith-based novel.
