If you don't want to know the circumstances surrounding today's entry in this slideshow, then don't read any further...
[spoiler]Today's quote:
Ep #99 (1966) - Burke - 'No one MUST know there's ever been any connection between you and me.'
From "#0099/0100: Robservations 07/31/01: Pen-Man-Ship"
I won't give up, she vows. Good, he says. I know, whatever happens, I have to stay in that house--I owe it to Mr. Malloy--you know I feel more than ever that the key to his murderer is somewhere in Collinwood. I know, says Burke--it's somewhere in that house--by the way, don't call me from Collinwood, it's too risky--no one must know there's ever been any connection between you and me. Somebody in that house already does know, she tells him. What? asks Burke.

The Robservations passage doesn't make it clear, but you can probably already deduce that Burke is speaking with Mrs. Johnson.
And, you might think it's shocking that I don't have a quote regarding THE PEN. But trust me, those are coming. And actually, THE PEN references are in Ep #100, not this one...
