Patricia Russo (whom you might remember from excellent stories in Not One of Us, among other places, though she hasn't written any recently) was the one who told me, and she mentioned Sapphire and Steel. I in turn told her that although I'd never seen that show, you'd written about it evocatively.

Of course I remember her! I miss her stories. I didn't know she watched Sapphire & Steel, but it fits when you tell me. I'm glad you have been enjoying NCIS.
