WHAT IS IT ABOUT?
An unscrupulous landlord, Sergeant Bouncer, has hit on a capital plan for maximising his income: he rents out his spare room both to Mr. Cox, who works all day for a hatter and doesn't come home till night, and to Mr. Box, who works all night at a newspaper printer's and doesn't come home till morning. So Sergeant Bouncer gets double rent for his room, and neither of his tenants is any the wiser! What could possibly go wrong?
