Is it clear whether the maid would have been an employee of the McCann's or an employee of the hotel? An employee of the hotel (former) would be in the area, I suppose. But would a former employee of the McCanns be in the area? Would she have been fired while on the trip?
I'm not sure I get it.
Would a former employee of the hotel kidnap a child guest to make her employers look bad? Sure, I guess. But now you've got a kidnapped child on your hands. What's next?
Would she have planned to allow the child to be found and maybe something went wrong? It's awfully complicated and not very personal (in the way that an employee of the McCanns kinapping their child would be). Easier to talk down the hotel and her bosses on internet message boards, really.
I took it to mean the maid worked for them and left under “bad” circumstances - vowing revenge.
I would not pretend to know or understand women, despite being married for 3+ decades. But when someone says they will get revenge, well, I would put them at the top of my list for a nice long chat.
I think the maid was an employee of the hotel.
