Marshal Zeringue just posted the results of my "Page 69 Test" of Murder on the Orient Espresso on his blog. It really was great fun.
The idea is to look at page 69 of my book (Murder on the Orient Espresso, in this case) and "discuss whether it's representative of the rest of the book and if a reader skimming that page would be inclined to read on."
As Marshal says, "The answer gives you an opportunity to say something about what your book really is about and how that page fits in or . . . whatever you like."
