You ordered the coal here all right, but I didn't have the kind you wanted, and so turned the order over to Brown. It was Brown delivered your coal: he's the man you owe." Whereupon Mr. Everyman goes to Brown's office; and Brown takes down a ledger, does a bit of original research in his Private Record Office, which happily confirms the researches of Smith; and Mr. Everyman pays his bill, and in the evening, after returning from the Country Club, makes a further search in another collection of documents, where, sure enough, he finds a bill from Brown, properly drawn, for twenty tons of stove coal, $1017.20. The research is now completed. Since his mind rests satisfied, Mr. Everyman has found the explanation of the series of events that concerned him.
