Summary

A man in a trench coat enters a room filled with several people. He asks tells not anyone no-one to leave the room in a variety of ways. A man with a pipe suggests he doesn't want anyone to leave the room. The man agrees pointing his finger at the pipe man. He then allows himself to introduce himself as Inspector Tiger. "Tiger?", the people ask and he turns around anxiously asking: "Where?"
He continues to explain that he is investigating a murder, when the man with the pipe informs him that there hadn't been any. He doesn't like it and sits down on the couch. The lights go out, there is a gunshot, someone screams and when the lights go on again, Tiger has an arrow through his throat and is dead.
Then enters another man in a trench coat, introducing himself as Chief Superintendent Lookoutoftheyard, who dies under similar circumstances. Another man enters, introducing himself as Chief Constable Theresamanbehindyou. Summarizing the events so far, he asks his accompanying Constable to play the part of Tiger, and shoots him in the course of it.
Finally enters another Constable, who excuses himself to introlow (I don't know what you meant here) his body, when a blackboard shows the number of Inspectors and Constables deceased so far.
