A We looked all around and could not find a speak, or windows that had the appearance of having been raised, or attempted from the outside, the back kitchen door, parlor door was fastened on the inside.

I was just thinking (talking to myself, or so it seems).

I have always thought that they entered through the parlor door.
There were two external doors on the front porch, one leading into the parlor and one into the kitchen/dining area, as well as the external back door.

From re-reading all the accounts, it appears that the key that Ross Moore had was to the kitchen/dining door, not the parlor door.

That was the door that was apparently also used by Josiah and his family.
Normally, that door would be locked with the key left on the inside.
However, the key was missing from that door.

We know that the back door key was still in the lock.
The parlor door was 'fastened on the inside'.
Not sure what this means, perhaps there was a latch.

So the only door that had a key missing, (and the door ordinarily used to enter and exit the house), with a key that would have normally been on the inside and was missing, was coincidentally the exact door that Ross Moore had the key to?? It was the first door he tried to open and opened it with the first key he tried. Hmmmmmmm.
