In principle, if you have read the first book, you have everything
you need to build a class set following any given pattern.

AFAIK, Design Patterns are not skeletons of code: they are mainly 
scenarios or models of behavior that appear to be useful in certain 
situations. Many of them can be modeled as a first approx. using a 
given skeleton of code, and many times this will suffice.  But the 
idea behind them is more "abstract".
