over 600 precise moves to open, the Acerbus
is the most
complex box ever to be created by
LeMarchand. Most of the separate plates have their own
movement, and the metal the plates are constructed from varies across
its surface. Many are silver but some are largely osmium, a
poisonous metal that can kill by absorption into the bloodstream
through the skin.
LeMarchand had used this metal once previously, on a box called "Enigme"
Unlike Enigme, Acerbus can be opened without ever having to touch
the poisoned plates, provided that the correct method is known by it's
worker. Bearing in mind the complex process
needed for this task, the worker would require the secret in advance in
order for this
to be possible.
The Acerbus Configuration has so far had 256 owners. This is
known due to the fact that each owner has written part of the box's
moves down as they have discovered them, and this manuscript filled
code has passed from owner to owner. It is
thought that a mere 22 moves remain undiscovered.
The current owner of the manuscript is not, however, the current owner

collection the original "Box
sold the Acerbus Configuration for an undisclosed sum to an
Armenian scholar, but retained the manuscript to sell separately. He

manuscript and its secrets, leaving only the first page behind in his
