"Of course he was," Wolfe said. "He had died of anthrax. Pratt mentioned at dinner Monday evening that he had first tried to buy Caesar from you, for his whimsical barbecue, more than six weeks ago, and you had indignantly refused. Then the anthrax came. Your herd was almost entirely de- stroyed. One morning you found that Caesar was dead. In your desperation an ingenious notion occurred to you. Buckingham, who resembled Caesar superficially but was worth only a fraction of his value, was alive and well. You announced that Buckingham had died, and the carcass was destroyed; and you told Pratt that he could have Caesar. You couldn't have swindled a stockman like that, for the deception would soon have been found out; but the swindle was in fact no injury to Pratt, since Buckingham would make just as good roast beef as Caesar would have made. Of course, amusing myself with the puzzle Monday evening, I knew nothing of Buck- ingham, but one of the probabilities which I accepted was that you had delivered another bull instead of Caesar, and that Caesar was dead.
