The Mystery of the Leaping Fish

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.
