Knockdown

Jacobia "Jake" Tiptree is deep in her latest home improvement project - repainting the porch of her lovingly restored house in Eastport, Maine - when she notices the man repeatedly biking past her house. His face is unsettlingly familiar, but his chilling message seems inexplicable: Blood shows up again. Murder will out. Then there's the anonymous email warning her to beware the Fourth of July - just two days away.
Jake remembers some shady characters from her days as a hotshot financial manager, but she's baffled as to the identity of her nemesis-until she receives a photo of a murdered man. From home invasion to kidnapping, this twisted killer is slowly but surely plotting a knockdown, not just for Jake but for the entire town of Eastport.
