This classic, though rather lofty straight Billiard takes its name from Count Negretto Sylvius, the rather aptly-named villain of The Adventure of the Mazarin Stone
. Negretto being derived from the Latin for "black", and Sylvius that for "wood", the name is an obvious allusion to the murky forests of so many fables - and fitting to a character whom Sherlock spends much of the story waiting for through the night, in expectation that the nobleman-turned-diamond-thief will come to try and assassinate him. It is presented here in a dark black-and-red sandblast, accented with a band of bright sterling silver.
