LeMarchand's first and arguably most classic, puzzle construct.
Its complexity was managed by expanding on the design of a similar box
designed and constructed by Albertus Magnus in the thirteenth century.
When operated properly, a pleasing melody issues from within which
belies its true nature.

"The boxes, known in some circles as LeMarchand Boxes, were each one of a kind
creations which were also puzzles, with the answer to one's ultimate hearts desire as
their solution."

"Each box is unique for each person, a different puzzle requiring a different solution,
a solution that is a ritual. It can never be easy to solve the box; it is something someone
has to work at, and something someone has to want."

"It is believed that LeMarchand constructed more than 270 of his puzzle boxes before he vanished. These
boxes change hands rapidly, as is expected, though there are a few collecters, who are interested in the boxes as objects of admiration, and have no interest in working their wonders."

"...By his 88th year, Phillip LeMarchand had gone far beyond that first small puzzle.
He had become one of hell's most prolific prodigies, eventually returning to his architectural
education to design entire buildings that were puzzles in themselves."

Philip LeMarchand allegedly murdered fourteen
persons in order to construct his first box.
