Fun with Mysteries in the Sci-Fi

I’ve been having fun with a character temporarily called “Mystery hands.” Starting in book one Earth and Beyond, and continuing in Ripped Genes, there is a series of short scenes in which hands carry out suspicious activities in a lab or medical setting. I look forward to the reveal in book three! Meanwhile, the idea is to personify the hands themselves. Why would I do that? Purely for the mysterious fun. The questions asked by the reader are not just “What is going on,” but also, “Who is doing this?” Since characters are the heart and soul of the MedSci Missions stories, the “who” is as important as “What in the galaxy is going on?” The hint I’ll give is that the hands belong to a character known to the reader. As for the science, I can’t say too much without giving away one of the long-term plot threads. I can say that BinDNA is described at the beginning of Ripped Genes as “bound DNA.” That means the alien infectious DNA has a chemical additive that binds up portions of the single-stranded alien DNA so it can’t pair up with human DNA and infect people. Thus, the BinDNA is safe to use in the lab as the scientists try to solve the big mystery, Earth’s pandemic.
