I don't understand why these writers think it is a good idea to never show the main suspect getting arrested or captured. Dr. Bennett would be able to take his yacht far away to avoid capture so it doesn't seem resolved because they also have yet to exactly locate the woman's body to get probable to file murder charges. The boat captain's body floating in the water didn't lead to evidence as far as we know. A resolution is far from a forgone conclusion. Very strange story writing.
