Pygmalion? What does the Websters Dictionary say?

[cinnabar]

One of the puzzles in this month's Crossword magazine has several Playfair encoded entries, from which the keyword can be deduced as Pygmalion. I am quite certain about this - it solves all of the encoded entires, and gives the encoded hint as 'Peruse Websters'. And according to the rubric, the keyword "is the alternative name of that which is used to complete the grid's unclued entry."
The unclued entry (15 letters, no number of words given) is __NT_N_I_L_RO__ but I can't make this fit with anything relevant to the Pygmalion theme. And the on-line version of Websters is no help either.
Can somebody please help with a suggestion as to what the unclued entry might be - either from the Websters entry or elsewhere?

I haven't got a clue what this is all about, however, from the letters given above,
you could make Pentonville Road ? Is that any help? If not, perhaps someone else may have an idea.

Did a search for that earlier and the only connection I could find is that Shaw wrote to the press about Roger Casement just days before he was hanged in that prison, but no direct connection with Pygmalion.

I went onto Google to see if I could find a link with Pygmalion and your question came up. We are in exactly the same position and the answer here, Pentonville Road, seems very convincing but we can find no reason for it.
We haven't found Hercule Poirot or the rest of the sequence in the other puzzle. Have you?

Hi Ruthrobin
I'm having trouble with both the crosswords as well
I think the Poirot one has something to do with his demise in the play Curtain, but have no idea what. Also 'expanding the series' one, two, three, four, five to get 22 cells (not 42 cells, as there aren't ant) - what does this mean?

[Ripper]

Hi again Ruthrobin
Hercule Poirot can be found at number 1,2,3,4 etc........ it'll make sense when you look at the grid!

[Ruthrobin]

Many thanks, I had highlighted those cells without realising that they were the ones containing the numbers. I still haven't seen the extension of the series.

For the other one, a kind friend has pointed out to me that there is a link between the colours and Pygmalion (look up brown) or email me at [email protected] if that doesn't give you the answer.
