He was in England incognito (I cannot imagine why) and took such delight in gliding down unfrequented ways and adopting strange aliases: visiting me by stealth after dusk with an agreeable suggestion of dark lanterns and disguise cloaks, though, as he was almost unknown in London, he might have walked at noon down Piccadilly accompanied by a brass band without anyone being much the wiser; Whistler, who also loved to play at secrets, was equally clandestine; I dutifully acting under orders, dissembled energetically, and Montesquiou was so wrapped about in thick mystery that no intelligent acquaintance within the three mile radius could possibly have failed to notice him.

---Graham Robertson, on Count Robert de Montesquiou, quoted in Edgar Munhall, Whistler and Montesquiou: the Butterfly and the Bat
