GL: Who killed Philip Spaulding?

GL has so many storylines going--make that so many GOOD storylines going--that we have kinds a lost sight of the "who killed Philip" mystery.

Of course, Beth has been acting suspicious which should eliminate her from contention (the writers couldn't possibly be that obvious, could they?)

The thing is--everything else has been so riveting that you don't even notice the lack of addressing this open issue the past few days.
