fishy

I know this is a very old topic, but if anyone is still around. I have double and triple checked the coordinates but i still cant seem to find it. (93,108) (133,78) (173,48) (213,48) (253,78) (293,108) These are my coordinates, and it gives me room 15, 18. But i cannooot find the book. Anyone able to double check if i still might have it wrong?
