Lord Marmaduke Ffogg and his sister, Lady Penelope Peasoup, are well known throughout Londinium as typical upper-class citizens. But in fact, they led quite a different life away from the public eye. They started a ladies' finishing school on their estate, which claimed to teach young girls how to fend for themselves, but in actuality trained young thieves.
And the lord and lady themselves had a habit of breaking into the homes of Londinium aristocrats and removing their valuables. After baffling the inspectors at venerable Ireland Yard for some time, Batman and Robin were called in to investigate. Within moments after arriving, Batman suspected who the culprits were and wrapped the case up not long afterwards.
