The Mystery of the Leaping Fish
1916
Coke Ennyday, the scientific detective, divides his time into periods of "Sleep", "Eat", "Dope" and "Drinks". In fact, he overcomes every situation with drugs: consuming cocaine to increase his energy or injecting it in his opponents to incapacitate them. To help the police, he tracks down a contraband of opium (which he eagerly tastes) transported within "leaping fishes", saving a "fish-blower" girl from blackmail along the way.
