The First Con *Spoilers*
The success of this is all dependent on Jonas not checking Louise's well being. If he had, the gig was up straight away, seeing she was just pretending for goodness sake.
Believe me when I say from personal experience, corpses look a lot different from live people. Of course he doesn't check, just sticks his head in the door and then starts getting rid of incriminating evidence on the basis of a quick look with no checking of vital signs. Just rather weird IMO.🐭
