Have to say, I love it. I'm not one of those who shut themselves away and refuse to hand out sweets to passing trick-or-treaters, muttering about how it's all those Americans' fault, and it didn't used to be like this. (If you catch an adult doing this, you can always ask them if they like a traditional Christmas; if they say yes, you can then remind them that we owe both today's Santa Claus and the Christmas turkey to our American cousins.)
I think the whole trick-or-treat thing is fun – well, as long as no trick is involved, which is usually the case. And it has its origins in the British tradition of souling anyway; that got exported to America, the Americans did their own thing with it, and exported it back to the UK. As indeed they have done with Shakespeare plays, breakfast cereals and Britain's Got Talent. And the jack-o-lantern, incidentally, has Irish origins.
Finally, a couple of special mentions: I'm currently reading The Undrowned Child, by Michelle Lovric (Orion): although more fantasy than thriller (though it is thrilling!) this contains the best evocation of a creepy, ghost-ridden Venice I have ever read. It's currently only available in hardback, but worth it, I reckon! When Teo comes to Venice with her parents, she soon vanishes "between-the-Linings" of the city; neither living nor dead. It is not until she encounters the mermaids that she discovers why...
Also worth a mention, since so many people tell me it's brilliant, is King Death's Garden, by Ann Halam (Orchard Books); unfortunately it's currently out of print. See if you can get hold of a library copy, or a second-hand one.
Well, there you have it; happy Halloween reading! Keep something humourous by your bedside too, in case you need some comforting – maybe even a Lulu Baker book (Chocolate Wishes, incidentally, has a very funny Halloween scene: see page 143). And don't forget to email me through my website, and tell me what you think of the TV show, as I shall be blogging about your reactions...but please remember, it's not meant to be the same as the books!
