Typo on Lancelot. Also, didn't accept characters from arthurian legend. Good grid otherwise.

It's actually "Tricia". Very good grid though, nice use of red herrings.

Nice red herrings made this a fun grid to solve. I can forgive the typos ;)

My spelling correction is playing tricks on me sometimes for English is not my first language (Lancelot is spelled with a z in German). Still sorry I didn't look up the real spelling of Tricia, thought I could trust me memory (since she's mostly just called Trillian in the novels).
Still hope you have fun with it :)

Mach weiter Pfaurenz. Ich habe MHD in Mainz studiert und hätte lieber Parzival von Wolfram von Eschenbach gesehen (Parsifal ist Wagner). Ich habe dein Rätsel genossen. Ich mache dir eins über Cricket and Bog-snorkeling.

If you're a fan of the book, this one separates quite readily, typos or no typos :-) H2G2 generated a few good grids a while back because ford and Arthur are both US presidents and of course lincoln is also a car...
