Bikini Beach Terror. Triple Jeopardy, #2

Paranormal, LLC are a trio of attractive young women trying to make it as ghost hunters.  However, most of their threats are earthly rather than spiritual. Gloria, Angie, and Lián's second case involves some strange goings-on at a beachside home under renovation.  Despite Gloria's best efforts, Angie and Lián are more interested in beach time than ghost-hunting.  Gloria finally gives in and lets the other two have some R&R before starting work.  When they return, however, their luggage is missing along with the keys to their van.  Things go from bad to worse as the team begin disappearing.
Oh, and the phantom of a recently-deceased woman is walking around, too.  Is she the source of Paranormal, LLC's problems, or is it something else entirely?
