The envelope said: “To Doctor Jacques.”

Here’s what the note inside said:

Hi, Bob.
This is the gal you’ve picked out as your replacement, so train her well. You’ve been a real jackass to her, so if you’re worth those extra three I.Q. points you’re so proud of, you won’t mention who you are. I’ll be back at the house Saturday afternoon.
Good luck (and I mean that),
Ben
