NCIS - Tell-All

An OK episode of NCIS, in that there are a number of red herrings but the final resolution was a little anti-climactic.
A Navy officer is found murdered, killed by a prototype weapon, then a a female officer is found strangled to death but no defensive wounds.  They are linked together because they both read a manuscript for a book that was a 'tell-all' regarding a secret operation to identify terrorists, Operation:Birdsong.
Not a lot else happens in this episode except that a character that is introduced near the end is another red herring (what was the point of that?).  Oh and Gibbs' and Fornell's ex-wife is getting married again.
