Attributed in George Bernard Shaw, Mrs.Warren's Profession (1898). This wasWellington's alleged response in 1824 to a blackmail threat from a publisher about to release the Memoirs of courtesan Harriette Wilson, who had been the duke's mistress and was ready to "name names." These words supposedly were written in bright red ink on the blackmailing letter, with the letter then returned to the publisher. However, the letter survives at Apsley House and has no trace of such a reply.
