For some time now, my head was buzzing with a lot of cars driving in Kendall, parked, reversed, drove back, rested, drove crazy and what not all. I wonder, why William did not have to stay close to the house or was guarded, if the property did not have at least a secure fence and if the child was still a stranger there, which means, William was probably more at risk than in his usual environment (though a "village idyll" and no big city). William also was certainly more curious than in his usual environment, especially when he was asked to wait for his father's return. I'm not thinking of a possible (pedophile?) kidnapper, who could have waited on the street - who's counting on that? I just think about the risk for William to run into the street (and in front of driving cars) or get lost on the many large plots (with their special unknown dangers).
In my mind, all the things, we hear, don't fit well together in some way. Okay, if we wouldn't have heard/learned of an abduction (or an accident), we wouldn't have interest in these details and all would seem to have been a normal morning in a small village. But unfortunately little William disappeared and now all the details are of interest, as always in cases like this.
