Miscellany
Walter Kirke, British deputy head of military intelligence in France, noted in his diary in October 1915 that the chief (“C”) of the Secret Intelligence Service had come upon a solution for how to send secret messages: “Heard from C that the best invisible ink is semen,” Kirke wrote. The substance, it turned out, was hard to detect by the common revealing method of iodine vapor. The chief’s name: Mansfield Cumming.
Guard more faithfully the secret which is confided to you than the money which is entrusted to your care.
—Isocrates, c. 370 BC
