BAFAB Day No. 4

Welcome to Day 4 of Buy a
Friend a Book's First Anniversary Contest!

Buy a Friend a Book -- the site that urges visitors to surprise their
friends with the gift of books during four quarterly BAFAB weeks a
year -- is throwing a week-long puzzle contest to celebrate the
site's first anniversary. Every day from July 1st to July 6th a new
puzzle will be unveiled at one of the literary sites helping out with
BAFAB's First Anniversary Contest. Books, Inq. is your co-host for
the fourth day of the puzzle. Contest participants will be asked to
solve six puzzles during the course of the week and to answer a final
question on the contest's seventh day.

Three winners will be drawn at random from all the correct responses
received. The winners will win hundreds of dollars worth of
literary stuff--stacks of books and free memberships in
LibraryThing and even a text editor. See the complete prize list here and the official rules here.

If you're discovering this contest a little late in the week, don't
worry. After they are initially announced, all six puzzles will
remain available for the duration of the contest. Thus contestants
who learn of the puzzle later in the week will not be barred from
participating.

Here's the complete schedule of events:

July 1 -- Puzzle #1 introduced at Grumpy Old Bookman
July 2 -- Puzzle #2 introduced at Confessions of an Idiosyncratic Mind
July 3 -- Puzzle #3 introduced at This Writing Life
July 4 -- Puzzle #4 introduced at Books, Inq.
July 5 -- Puzzle #5 introduced at Refrigerator Door
July 6 -- Puzzle #6 introduced at No Rules. Just Write
July 7 -- Final question posed at Buy a Friend a Book

Today's puzzle is a secret picture.

First go to Buy a Friend a Book to print out a larger version of the picture you see to the right. Then shade in all the blocks in the picture in which there appears the title of a work written by Patricia Highsmith, whether it be a novel, short story, or collection of stories. Don't be fooled by the made-up titles that are scattered about the picture! Nor by the fact that at least one of Highsmith's novels was published under two different titles: both appear here.
Good luck!
