Help me with my new book!

So the editing and revising and outside input and all is working well, rapidly turning my first murder mystery from a stinking heap of random words into an MS that I can be proud of.  But I'm totally stuck on one particular point:

The Title

That's right.  I've been working on this for years, and have never lit on a title that I really like.  So I'm going to give you the two-bit summary and a list of possible titles and let you vote.

Pismawallops Island is a quiet place where nothing much happens, even at the High School.  That’s why JJ MacGregor likes it.  When a rogue member of the PTA threatens to disrupt the even tenor of life in the middle of Puget Sound, JJ wants someone to take a firm stand.  When Letitia Lemoine shows up very dead in the freezer where there should have been 30 boxes of ice cream bars, JJ worries that someone might have taken her command too seriously.  Not the sort to sit back while someone else solves her problems, JJ just can’t help asking a few questions.  But someone wants her to stop—and a loud mouth and insatiable curiosity can be a dangerous combination.

And here are the possible titles:

Death Stalks the PTA

The Corpse in the Ice Cream

Murder a la Mode--please ignore this option--it's been done, more than once!

Death By Ice Cream

Fundraisers Can Be Fatal

The poll is over there in the side-bar, because I can't figure out how to put it right here.  ~~~>

Oh--and if you have a better idea, speak up!  I'll even give you credit!
