Jughead Jones; Archie Andrews; Veronica Lodge; Mr. Lodge
Jughead cleans windows at Veronica's house with the idea that he will be invited to the big meal being brought in. Jughead writes on the window-side of the blinds while he's cleaning the windows. The sign says "Open House Free Food." and various hoboes come for the meal.
Pop Tate is very excited about Jughead coming, because it's the day Jughead gets his allowance, so Pop serves him whatever he wants. The only thing Jughead wants is water. He won't get his allowance until tomorrow.
Jughead impresses the gang with his powers of deduction, so Reggie tries to set him up. Jughead has to find a pin stolen from the safe. He follows clues such as rice grains and Chinese laundries, but after he finds the pin and Reggie leaves, Jughead admits that he used the window clue, as in looking in it to see where they hid the pin.
