I am so mad....what is this world coming to???

So I bought the book 'The Da Vinci Code' this past friday b/c it came well recommended. I've been reading it all weekend and was half-way through. I went to the car wash today and I took it out of the car so it wouldn't get lost and wouldn't you know I left it on the counter after I paid. I went back in a few minutes later and it was gone. The cashier said she saw the book there and saw some lady quickly put it in her bag. When I went back outside she was of course speeding off.

What is this world coming too....where people are now going around stealing books?? I was upset and started crying, then I was just really mad b/c the book was good so far.
