The Mystery of the Leaping Fish is a 1916 American short silent comedy film starring Douglas Fairbanks, Bessie Love, and Alma Rubens.

The embedded story shows an investigation led by Coke Ennyday: this private detective, who makes an immoderate and constant use of drugs, including cocaine, is hired by the local police of Short Beach to discover the real means of subsistence of an extremely wealthy and mysterious man.

Incidentally, Joe also wants to force Inane (a female employee of the shop, whose work is to blow air into the inflatable mattresses) to marry him within a week.

In this unusually broad comedy for Fairbanks, the acrobatic leading man plays "Coke Ennyday", a cocaine-shooting detective who is a parody of Sherlock Holmes.

[4] Ennyday is given to injecting himself from a bandolier of syringes worn across his chest, and liberally helps himself to the contents of a hatbox-sized round container of white powder labeled "COCAINE" on his desk.

[5] Fairbanks' character otherwise lampoons Sherlock Holmes with checkered detective hat, clothes and even car, along with the aforementioned propensity for injecting cocaine whenever he feels momentarily down, then laughing with delight.
