AND ME WITHOUT MY SECRET LITTLE ORPHAN ANNIE DECODER RING!

Plowing through the Da Vinci book. Imagine an arcane book like this being written by a guy who calls himself Dan Brown, instead of Horace Snigglefritz or something. When I got to the secret mirror image poem in the rosewood box I very cleverly held it up to the light from the rear to see what it said in reverse, not realizing that the author had already reversed the image for us and it had been written in some kind of Spencerian script which I couldn't read even from the front. Gah! I am not much of a decoder!
