WPC Marieke versus the chair

‘I have two pairs of Speedcuffs!’, Marieke tells us excitedly. Well, she shouldn’t have said that… We have one chair, but it proves to be a worthy opponent for copgirl Marieke. She struggles to move her wrists up and down the chair’s back, but her fingers can’t reach the keyholes. Marieke puts up a very good fight, she may work this puzzle out, but then again… it will be much nicer if she doesn’t!
