During the short railway journey to Swapshire, Herlock Sholmes plied Baron Battledore with questions.

“Have you any enemies of whom you are aware, your lordship?”

The baron looked surprised.

“Scores,” he replied; “the income-tax officials, the whole Labour Party in the House of Commons, a butler named Spivet, whom I dismissed recently for possessing a whistle — “

“A whistle!” I cried.

“A whistle!” repeated the baron. “He was always whetting it – with my rare old wines!”
