„Dr. Delmore's Secret" is an absorbing tale of mystery by Fenton Ash, author of at least three Lost-World novels. Little is known about Aubrey/Atkins. He was involved in a scandal at the turn of the century and sentenced to nine months imprisonment for obtaining money by deception. After leaving prison he dropped the name Frank Aubrey and – in his early 60s, following a three-year hiatus – began writing as Fenton Ash.
