Why Am I Involved With This?
'' Maria: I had a dream last night. It was a strange one. I was in my kitchen, putting the dishes in the dish dryer like I always do. I turned and saw a newspaper on the counter. I picked it up and read the headline story: MATT EVANS FOILS SUPERVILLAIN’S PLOT: TOWN SAFE ONCE MORE. I knew it must be a sign, so I tried to make sure you weren’t around to foil my plans. ''

'' Matt: So the handcuffs on the bed? ''

'' Maria: Me. ''

 You ponder a second and realize something:

 There's No Motive for this Crime

 Why Did You Leave the Key to the Handcuffs Next to the Bed?

 You Don't Have a Dish Dryer!
