Okay - here's the deal: Britney Spears and Lindsey Lohan are making a picture on Martha's Vineyard. Also in the movie is Patrick Stewart, and to mix things up, Paris Hilton is strirring up trouble.... then there's a murder.....
No - that's not REALLY what the book is about, but the cast of characters and location are a recoding or recasting of differently named characters who are equivalents of the aforementioned people. And Haddam makes clear she's aware of the alter-characters she's created by referring to Hilton and Spears - though NOT Patrick Stewart.
AND... it's a great story. Admittedly, I'm a sucker for every Demarkian book Haddam has written. I like the characters, I like the way they think, I like the way they THINK about thinking. I love Father Tibor, who barely appears at all in this book - but still has a presence as other people think about him and what and how he'd react to things.
