It took less time than I thought for ghosts to be declared citizens after the planes overlapped; it took even less time for me to get a sign up on my door proclaiming me a “Detective with Ghostly Interests in Mind.” They come see me to straighten out bigamy issues or get their names cleared (somewhat belatedly). I listen to their stories, take their funds (all digital now anyway), and resolve every case–never had a single complaint. Of course none of them notice that my expertise comes from being trained in exorcisms by the Vatican. Requiescant in pace, indeed.
