That river in Egypt

Windows were just inconvenient doors waiting to be made. He wouldn't be able to get the cuffs or the chair off, nor unlock the front door. But if he got a good 'run-up' he could hopefully jump into the window with enough forced to break through it. From there he could shuffle away to safety, well away from this damn house and she wouldn't be able to find him. He wouldn't be very quick due to the cuffs around his ankles, but this was his only chance to get out of there. He bent over, picked up the chair behind him and shuffled over to the window. On the outside it was just garden, hopefully a soft landing. There was no gate on that side of the house preventing him from making it to the street from there. He'd better go now or she might see him on his escape and catch up.
