Before you started answering this question, had you already used your one permitted lie?

Yes (6/20)

Very clever question! Had I only had bonus points to give away...

I'm sorry to say, but I'm leaving the country in a few hours - so this quiz will not be resolved until I'm back (Wed, 23rd).

I wonder if Hakan is heading this was for an attempt to get his record back! That's not a question by the way. :)
One day I shall return!

Being even more cunning... that answer could have been the lie.

Or is that just paranoia?

I think jbom1's original question was cunning enough to exclude that possibility :)
Well pointed out. I hadn't read it that way.

Paranoia it was, and that didn't use up a question point :)

Not sure if I'm missing something, but I don't see how we can rule out the possibility of jbom's question being the lie. I'm desperately trying to think of a way to construct a question to do that (something like "Have all previous questions been answered at least as truthfully as this one?") but I don't think there is one...

However, we can now be 100% sure that any answers from now on will be truthful.

Agreed. We know that there has been exactly one lie so far and that the remaining answers will be truthful. However, if Hakan had not lied already, he had the option of using his one lie in response to my question. Either having lied once previously, or using the lie in response to my question, would give the answer YES. In either case, the lie has now been expended. However, if he used it for my question, all the previous location-related answers would have been truthful.

Had he answered NO, we would know that every answer so far had been truthful.

Right then. Any station which is excluded by two (or more) answers can be decisively ruled out, because otherwise they'd have to be both lies.

Questions 3+4 together exclude all of Zone 1, except for Tower Gateway which is excluded by questions 4+5 together.
Questions 2+4 together exclude all of the District, H+C, Metropolitan and ELL (assuming the former ELL stations still count as "being on a sub-surface line" :))
Everything else is still in play.
All future answers will be truthful.
So, with that in mind:

Are you on an overground line?

Yes (6/20)

BTW I use this map for my answers, and I'd use the concept of east, west, north and south to mean right, left, up and down on that map.

This implies that I made a mess in my first post -

* Any line is ALWAYS EXACTLY ONE OF: Overground, Underground and DLR.
* Underground is subdivided in two mutually exclusive sets of lines: Tube and SSL (Sub-Surface Lines)
- obviously it should read:
* Any line is ALWAYS EXACTLY ONE OF: Overground, Underground, DLR and Bus (ELL repl bus).
* Underground is subdivided in two mutually exclusive sets of lines: Tube and SSL (Sub-Surface Lines)

I.e. so far:

Are you inside the "Bottle" ? - No (1/20)
Are you on a sub surface line? - No (2/20)
Are you outside Z1? - Yes (3/20)
Are you on a Tube line? - No (4/20)
Are you on the DLR? - No (5/20)
Before you started answering this question, had you already used your one permitted lie? - Yes (6/20)
Are you on an overground line? - Yes (7/20)

I'm a little disappointed that my post was seemingly ignored :(

Sorry, that would make it boring (in my mind)...

Oh, and one more rule, while I'm at it:

The "hider" cannot lie to a specific station guess!

Sorry Yorkie, that I ignored your question completely, but as you see from the above quotations, it was not a legal question at that point...

As you've so carefully defined the underground/overground*/DLR/bus categorisation, perhaps it would be worth clarifying where (if anywhere) the under-construction bits of the ELL extension fit into that scheme? Or am I getting far too picky now?

* (bah, I've got the Wombles theme tune in my head now)


Anyway, next question:
Does your station have a name consisting of exactly two words (counting '&' as a word if necessary)?
