If I could get just one Perl Book what should it be?

[Brian Jackson]

To all,

I have programmed in C, Fortran, C++, Java, Awk, Korn Shell, but  I am
new to Perl.   I already have a few quick reference documentation for
Perl in a Linux in a nutshell book.   I have money to buy just one Perl
book.   What is the best one book that I can get to teach me Perl??

Thanks in advance.
Brian
