Fifty: an adventure at Kap-Con, Wellington NZ this weekend, by Morgan Davie, with a disarmingly frank description:
It is also the Moffatiest adventure I could come up with... Oh, and I have no idea how to end it...
I’m sure it’ll go well anyway. Morgue is that good. (Damn him.)
Particularly amused that Doctor Who is also listed as genre and style.
