The novel has already shown how Addie is incapable of leaving her mark on the world, and her inability to use her thumbprint to unlock Henry’s computer is further evidence of this. Addie’s discovery of the engagement ring should make enough sense to the reader, who can logically assume that the ring was meant for Tabitha, the woman Henry is hung up over. But the presence of the bloody handkerchief wrapped around the ring adds a layer of tension and mystery to Henry’s past—what is he keeping from Addie, and does it have something to do with why he can remember her?
