I think Amsterdam is to Holland what New York is to America in a sense. It's a metropolis, so it's representative of Holland, but only a part of it - you know, it's more extreme, there's more happening, it's more liberal and more daring than the countryside in Holland is.
Historic Amsterdam, that old part you first see when you turn up at Centraal Station, may have its monuments, but it's also the most tawdry and overcrowded part of the city.
I know that I am very popular in Holland, in fact I have visited Amsterdam several times to publicize my books. I have a great publisher in Holland and they have published all of my books in Dutch.
