Femme Fatale

Help. I have reached a dead end. I am in the middle of several mission strings and can't find any new developments on any of them.
I have found two of the thor freighters and am awaiting a hint on Rigel IV.
I have started the stolen art thingy missions but they soon dried up.
I have allmost completed the Home murder mystery case, I am supposed to be "keeping my eyes open" around the galaxy or something like that.
I have been aroyund the galaxy many times and can't find any new leads.
Please help. Captain Birdseye.
