I have listened to this show several times so I listened to it again with the above comments in mind. I agree that it is a moral dilemna. Unfortunately, many people would probably push the button for a lot less than a million dollars. What has struck me every time I have listened, is that there can be no Honor Among Thieves. The first time around, the ending caught me completely off guard.
I also agree that the writing is top-notch. It seems many of the shows that have the great writing, have believable dialogue in "long takes", very dramatic, and in this show that is especially the case. The bedroom discussion of the "alternative" to Mrs. Van Haas' pregnancy is notable. From the "time capsule" standpoint, I got a kick out of the use of the word "chick", and the notion that a digital clock would be new and expensive.
It would be interesting to extrapolate, how Van Haas might have reacted when it slowly dawned on him that no check was in the mail, that he had murdered for nothing. Maybe he might have cracked up from guilt, or maybe he would have tried the ploy on someone else (there were mouths to feed...).
I think this is a four-star show and am always glad to listen to it again.
