Inspector Willoughby has traced evil international jewel thief and master of disguise Vampira Hyde to the Limehouse District in London. As Big Ben chimes out the hour of 4 p.m., Willoughby realizes that it's time for tea, and he enters a tearoom. He's served by a woman whose face is familiar to him. Suddenly, Willoughby recollects that she is the woman he's been seeking. She, in turn, realizes that she's been recognized, and by means of a pill, quickly swallowed, she quickly changes into a sweet, modest, elderly woman.
