just clues at the scene of the crime..eh?
Quote from MAESTRO:
Holmes is known to be moody and antisocial, cloistering himself in his rooms for weeks on end, brooding and indulging in his infamous drug habit. He started using morphine and cocaine as a student and became dependent upon his âseven-percent solutionâ of cocaine, mainlining it three times a day at the start of The Sign of Four. Watson admonishes him for his drug use, and in the later stories Holmes apparently has kicked his habit. It should be pointed out, however, that Holmesâs drug use was not illegal and would not be until the Dangerous Drug Acts of 1965 and 1967.
