I’ve no idea what that is – the only “logical” explanation is water running through the pipes, but it sounds awfully human for that. If it’s a ghost, the most likely candidate would be Pearl Conner, who disappeared along with her mother, Julia, around Christmas, 1891. As near as I can transcribe it, she’s saying “Sorry Beefalow,” which sounds like the worst Chef Boyardee product ever. There’s a recipe linked at the site above.
Others, however, have suggested that it’s “buried deep below.” Women, in particular, tend to hear “Why did she go,” which would be presumably a reference to her mother, who had been carrying on an affair with Holmes (according to her ex-husband, to whom Holmes subtly bragged about it). Assuming it’s a ghost, it could be any of these things; perhaps the lack of vocal chords makes it hard to form the sounds one intends to.
The three women whose names I’m whispering – Emeline Cigrand, Julia Conner, and Pearl Conner – are the three people I’m most confident Holmes killed in the castle. Anna Williams and Emily Van Tassel might have been killed on the north side, and the whole thing with Minnie Williams is just weird: alone among his wives and lovers, she seems to have had some idea of what was going on, and is the only woman he called his “wife” who vanished. That she killed Anna herself, as Holmes claimed, isn’t exactly impossible, and the possibility that she ran away instead of being murdered isn’t out of the question. Those are just about the only known Chicago victims. Most of the stories you hear about there being dozens or hundreds more come from 1940s pulps.
What DO you hear in the audio? “Why did she go?” A toilet flushing? I’m not normally one to get too interested in equipment readings; they usually require a of imagination to make you think they’re ghosts, and most can be explained away without too much trouble. That’s why I generally throw in a terrible recipe or something along with the “evidence” – as a researcher, this isn’t the sort of thing I take too terribly seriously. But little imagination is required with this one. Here’s a recipe for Sorry Beefalow!
