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 discovers a contraband of opium (which he eagerly tastes) transported within "leaping fishes", while thwarting the plot of a mysterious man to blackmail a lovely "fish blower" girl.
