Blue Bloods - My Funny Valentine

Ah, love is in the air, but not as you would think.  It's New York style and not in a Woody Allen type of way, unless you include Manhattan Murder Mystery!
A young girl is kidnapped for a ransom of $5million and Danny and his partner have to find her.  After a false alarm at the drop off of the ransom (a homeless man was given $100 to do the pick up), Danny figures out that perhaps the girl's boyfriend is behind the kidnapping and then it doesn't take much for him to theorise that the girl was in on it too.
Meanwhile, Police Commissioner Reagan can't help but notice his office cleaner is upset (hell, she smashes one of his mugs!) and she lets out that her son has been arrested but he is innocent (aren't they all?).  The Commissioner tells her he can't get involved, but since when has he ever done everything by the book.  He surreptitiously visits the detective on the case and asks her to have a second look.
Lastly, Erin's annoying daughter Nikki, buts her head in and invites her Mum's boss to Valentine's Day dinner!  She realises, just in time that she may have put her Mum in an awkward situation and talks to Granddad, who says to talk to her Mum about it, which she does and Erin quickly nips the dinner in the bud.  Her boss, who is running for Mayor, says that once he is elected he can stop hiding.
However, Danny's investigation takes a sinister turn for the worse when the kidnapped girl's boyfriend is found dead and it appears there is now a real kidnapper involved.  They manage to find him and the tied up girl but he kills himself, rather than be taken in by the police.  It appears the girl found out Daddy was going to marry his girlfriend but she wanted Mummy and Daddy to get back together and thought this was the best way!?!  So there was love in there somewhere!  Her and her boyfriend thought it up and it went south when they got the crazy guy involved, who ended up killing the boyfriend and taking the girl hostage for real.  Charming.
Also, the detective looking after the cleaner's son's case, advised the Commissioner that she had another look and the boy is innocent and has been let free.  Apparently it is true that is is not what you know but who.
Lastly, Erin turns up for Valentine's Day dinner to be greeted by all the single members of the Reagan family where they enjoy a dinner of Peking Duck! Happy Valentine's Day!
Not the best episode but a great twist to the kidnapping, even if the crazy guy kills himself.
