I have found a pack of playing cards my ex husband (ex since 95) left.
I remembered him always saying it wasn't a complete deck and there was a marked card in it he used for a trick.
I moved house recently and they surfaced again so decided to look a bit more closely and it strikes me this trick might actually be a curse of some sort. There were other strange items he kept in his desk along with these cards filed under 'misc'
Anyway, the marked card is the king of spades and the missing card is the 4 of clubs.
Someone told me this is bad news, but I'm a confirmed atheist so I have no fear of sky fairies of any description and I'd rather like to know what this means.
