And why, why, why did he need to reach her?
This is my $64,000 question!!!
He shouldn't have been surprised she was missing until he went to get in bed. I say 'bed' because I'm jumping off his perfect marriage claim.
He saw her, had dinner, she went to the kennel, he went to his Mom's. According to him. All pretty mundane. Why the sudden urgency, AM? Why did you need to make a show of trying to reach you had to reason to think was anywhere but a Moselle, house proper? Couldn't wait until you got there?
Bum luck when foreknowledge betrays you.
