Lost Again

Fiorella's card case is gone, the one from the 2015 New York RWA conference, the one she keeps her professional cards and her credit cards in. She knows she lost the case in the house, probably in the den or the front room, maybe the kitchen, and she's been searching up and down for it, with Minnesota son right behind her, but no luck. Now, Fio is no stranger to lost credit cards, and she lost the case at H-E-B once, but how can one lose a card case in one's own home?
