on/off-topic: Sheppy by Maugham, bookstores in London, Cardiff

[John Costello]

I'll be in Cardiff and London for about a week each in March, and I'm
hoping that I'll have better luck finding a copy of W. Somerset Maugham's
play Sheppey in the UK.  I'll also be in Hay-on-Wye, but those shops show
no sign of the play.

I would welcome recommendations on book shops that might have used (or 
new?) copies of the play, which last was published in, I think, 1977.

John
