So I am looking for an older episode but I do not remember a lot of it.

I know it took place in some kind of mansion outside of tokyo maybe not a mansion but a luxurious house or something similar.
In this case a number of people were killed not only one.
I know for sure that one person killed was drowned just outside the house in some kind of flower pot or fountain. I may be mixing up cases here but I do remember something about a game and each person was give a card but as I said this can be a mixup.

Well those are all the memorys I have of this episode I know its not a lot lol and probably fits a bunch of cases but maybe someone knows what case im searching :)

Thanks in advance
