I actually kind of figured out the float but I probably didn't figure out the tide part :/ but other than that... this case.. and majority of the cases here are a bit boring and bland.. (you can already tell how much Conan I read xD) The culprit was already shown from the start and once you see a float with punctures in them, it's not that hard to figure out how she died... But the motive for this and the man himself is truly a scum. he's basically just a gold digger and the girl barely did anything wrong (well for what's shown here..) Man I wish this guy died instead... (that's sometimes why I like reading Gosho's stories more since more often than not, the trashy people die)
