The scene: A room at 221b Baker Street...
I say Holmes, what do you make of the Tory Manifesto, it looks pretty thin gruel to me?
But Watson, did you not notice the significance of the reference to Crossrail 2 and perhaps more interestingly Network Rail?
Can't say I did Holmes, in fact I'm not even sure I saw them mentioned at all.
That, Watson, is the significance.
