Barbara leased a triplex from Dick Grayson. Barbara sublet one third of the triplex to her cousin Corra Grayson without Barbara's knowledge or permission. Corra was negligent while living in the triplex. She allowed the bath tub to overflow which caused substantial damaged. Upon discovering the situation, Dick Grayson notified Barbara that he was holding her responsible for any and all damages to Corra's portion of the triplex, and that Barbara was going to be responsible for making the property like it was prior to her renting it. Barbara replied that she had sublet to Corra in good faith, had no knowledge of negligence, and could not be held liable for damages caused by another.
