Elementary: "The Man with the Twisted Lip"
Elementary: "The Man with the Twisted Lip." Season 2, episode 21. 24 April 2014. Saith Mann, dir. Craig Sweeney and Steve Gottfried, script.
Elementary is Sherlock Holmes in the 21st century in, mostly, the relatively mundane world of New York City and is not SF. This episode, however, introduces drones of various kinds, at least one of which is immediately relevant: a spy drone of very small size for a drone that looks like an elegant jewelry rendition of a mosquito, picking up the themes of nano-technology (not mentioned in the dialog), surveillance, and what Ricard D. Erlich and Thomas P. Dunn have called "The Ovion/Cylon Alliance": the association of insects and the mechanical, or, in this case, presumably, electro-mechanical, and certainly electronic and cybernetic.
