The author uses very vague and mysterious phrases such as "as the website had promised" and " unlock the door with the key I had been sent.". Because he doesn't reveal who or what sent him/ brought him to that home, we question why he is there and what is going to happen next (Good or Bad). This can be seen in movies too. Typically writers will leave out key information to make us think and wonder. Hope that helped! :))
