Unfortunately I can't even remember the title other than to obviously say that number theory is in it somewhere. > > And of course, the FLT proofs: Dirichlet & Lagrange's for exponent 5, > Dirichlet's for exponent 14, and Lamé's for exponent 7 > Try Edwards' book on Fermat's Last Theorem (or whatever the correct title is; it's called a genetic intro. alg. no. thy., but I wouldn't trust my memory.) Or Ribenboim's book "13 Lectures on FLT". The only place I can really recall seeing Dirichlet's proofs is in his collected works.
