Shades of Aether3d render transparent

Amethyst Forester is a scientist, not a lady.

Benjamin Maker is a lord, trapped in a loveless marriage.

The only thing they have in common is Professor Richards – genius aetheric scientist and mutual friend. 

When Richards is found dead, Forester and Maker are put in an impossible situation, jointly inheriting his house, its contents – and the mystery of his murder. 

Could the Professor have been killed for one of his experiments? And if so, what if someone’s still looking for it?
