The Alchemist of Lilley, Hertfordshire, is the tale of Dr John Kellerman, a scientist and practising magician who honed his talent for the dark arts in his mansion-come-laboratory!
Kellerman’s mansion was supposedly converted into a highly-guarded fortress where the doctor would perform alchemy to create heaps of gold.
Once his secret got out and the fort was compromised, The Alchemist escaped through his skills of disappearance and vanished, along with his secret methods, forevermore.
