...........Exactly! Why would Dirk need to keep quiet about his wife's disappearance for 10 years, if Rachel was indeed murdered at sea, why is Dirk even involved? Nah, something tells me that Rachel is alive in Australia and 'something' did happen to keep Trevor and Dirk safe for ten years. Rachel had to be privy to much more information then the' sale' of the Aires to have her life in danger. More likely, she recognized Detective Alford at some point in the last charter, realized that Bridget's husbands death was either to coincidental or she witnessed it. After all, we know Arnold was killed, it was deemed an accident at he time (Sr. Detective Alford?) and it maybe be tied into to drugs. I think Lisa might be the key to unraveling this mystery, if she starts thinking about it, about what Bridget said to her and the boats occupants at the dock. Given her track history, I would not be surprised if she inadvertently discovers her father was not responsible by way of argument with him, for the 'e-mail' sent to Jim. Maybe she will remember that Bridget had that 'site' bookmarked.
