Little Sherlock Holmes, Jr., reads the doughty doings of his hero-god, and at once determines to become a detective himself. Providence at once favors him by giving him a mystery to solve. His father has noticed that in some weird, unaccountable fashion the whiskey in the decanter is ever vanishing, and father swears he drink it as fast as all that. So Sherlock Holmes, Jr. assigns himself the task of discovering who tampers with his father’s soothing beverage. Concealed behind a table, he sees Bridget, the cook, come in and at once proceed to get on the outside of a man’s size pull on the flask. At once the embryo detective makes his report to his father, with the astounding solution of the mystery. The father decides to use Dr. Brown’s Sure Cure for the Liquor Habit on the cook, and obtains a bottle of the fluid. This he puts in the room near the whiskey, intending to pour some in the bottle a little later. Sherlock Holmes, Jr., discovers the bottle and follows the ‘Do it Now’ maxim. There are friends visiting the house at the time, who are sitting on the lawn with his parents, awaiting tea, which the maid is going to bring them. Sherlock Holmes, Jr. pours a goodly amount of the fluid into the tea. One of the results of taking the liquid is falling into a deep slumber, and in a few moments the host, the hostess, and the guests are fast asleep. Then happen’s along Bridget’s beau, the policeman, for whose particular benefit Bridget essays to go inside and procure a glass of ‘buttermilk.’ After imbibing, the policeman forgets all about everything except that he is awful drowsy, and the next thing, he, too, is asleep. It must have been contagious - or could Bridget not have forgotten herself? - but at any rate, she, too, wanders off into the Land of Nod. Then Sherlock dons the policeman’s clothes and club, and marches through the house, monarch of all he surveys. At this opportune moment, two burglars arrive at the scene, and seeking the sleepers, think they have been transferred to Burglar’s Paradise. They sneak upstairs, fill their bags with silverware and then fall for the whiskey on the table, little Sherlock watching eagerly. At last they get themselves off, followed by the creator of all the mischief, but they have not gone far when they are overcome by the liquor cure and fall in their tracks to sleep. Little Sherlock now takes the manacles from the policeman’s coat pocket, and ties both legs of the burglars together. In due time the household awakes, they seek the boy, and eventually find him covering the two burglars, prisoners of Sherlock Holmes, Jr.
