This show is a pretty good mystery, at any given point each of the characters seems likely to be the killer. That said, I dislike this show for one reason: the waste of a great title. When I first listened to it 2 years ago I was drawn purely by the title. I expected some 16th c. drama involving alchemists, potions, treachery etc. I think the mystery could have been effective using some other centerpiece. I do think the sound effect itself was very good, but would it be real scary coming out of a cassette recorder?
