Lux,
The questions is - Which one London Underground station does not contain any of the letters from the word "mackerel"? For the life of me after having gone through the station list twice I cannot find any station which fits this.</font>
I'll give you a hint... It's as it's written on the tube map. For example, if something were written 'St' instead of 'Saint', then a, i and n are not included...
