Last one: 1d Having an atomic number greater than element 92. -r-n-i-a-i-m. I assume it's something titanium, and thus that 16a is spelt Nioc Man. Many thanks OB
Wow, that was quick! Thanks both of you; I was on the wrong track, so 16a can be Nuoc Man as I first thought. That's The Generalist and Saga finished by Saturday, previously unheard of in this house!
