Did anyone count the number of Agatha Christy titles in the script e.g N or M, Why didn't they ask Evans?.

I noticed that! I thoroughly enjoyed listening out for them all once I realised what was happening. 'Taken at the Flood' was another one. I didn't count them but there were an awful lot!

I enjoyed watching that episode, it really made your brain wonder. I lost count!

Erme - I'm actually writing a quiz about this episode because I enjoyed it so much. If and when it goes on line, I hope you'll all enjoy playing it as much as I enjoyed writing it. My favourite episode so far - ever ;-)
