“Star-Spangled Banner” lyrics. The first letter of the first word would be your “in” character, and the last letter of the second word would be your “out” character. So say your words were
“dawn’s” and “stripes.” You’d write out the alphabet starting with “D” from “dawn’s,” adding the “A,” “B,” and “C” at the end; and underneath these letters, you’d write it out again, but this time beginning with “S,” the last letter of “stripes.” Like this: D E F G H I J K L M N O P Q R S T U V W X Y Z A B C
S T U V W X Y Z A B C D E F G H I J K L M N O P Q R
You substituted the letters in the second line for the first line’s letters in your original text. So in the SSBSC dawn’s/stripes 138
cipher, ZNGHITC QAPZTCTN XH RWPGPRITGXOTS
QN GTRTHHTH PCS HWTAITGTS WDAADLH would
mean “Kyrsten Blakeney is characterized by recesses and sheltered hollows.”
All the recipient would need to know to decipher the message was where the alphabet began on each of the two lines. The way we used to do it was by number. “Dawn’s” is the eighth word in the SSB, and “stripes” is the twenty-third word. So the key to the Kyrsten Blakeney message would be SSB-F8-L23. We used “The Star-Spangled Banner” because we both knew the first twenty-six words of the lyrics by heart. The “F” and “L” stood for first and last, because sometimes we would vary what letters we would use, so we could have L/F or F/F, or even midword letters that we would identify by Roman numerals: SSB-8iii-23iv. It could get pretty complicated.
Even though the letters of the coded portion of Tit’s note were arranged in a neat little parallelogram rather than in one line like normal text, I was pretty sure it was some sort of cipher.
It is possible to solve a substitution cipher by trial and error, even without a key, but Tit’s message wasn’t long enough to gauge the frequency of commonly occurring letters like “E” or
“T,” which is how you usually begin. Plus, if I was right, he had broken his ordinary coded sentences into fourteen-character clumps, so you couldn’t even guess at common words like
“the” or “of,” though some of the double letters might have provided a clue. There was only one way to decipher it, practically speaking, and that was to discover the key. If it had been based on something they had memorized, like “The Star-Spangled Banner,” there was no hope of recovering it. For reasons I’ll get to in a second, however, I didn’t think it had been memorized.
In any case, there would likely have been some indication for the recipient of how the key should be applied, along the lines 139
of the SSB-F8-L23 notation I mentioned. My assumption was that it would be somewhere on the note itself.
At first I thought it might be in the body of the message, which was uncoded, but cryptic, and which indeed made almost as little sense as the cipher. But then I looked at the date. There are only thirty days in June, so the date 6/31
doesn’t exist. The original date, 5/31, does exist, of course.
Why had Tit scribbled out the five and written a six over it, changing a real date to an imaginary one?
Here was my idea on that:
What if my dad had underlined the passage in
Then I noticed something: counting letters instead of words, the fifth letter of the passage was “T” and so was the thirty-first. That wouldn’t have been any use for a substitution cipher, since the in and out letters would all have been the same. What if Tit had written “5/31” and then changed the five to a six when he realized the 5/31 combination wouldn’t work as a key? Sixth letter from the beginning was
“H,” and the thirty-first was “T. . . .”
Damn. It still didn’t work, not in any of the configurations I tried. Yet it seemed too much of a coincidence that Tit 140
would have happened to cross out a date that would not have worked as a key and replace it with one that would, if he hadn’t been working from that particular passage. And it explained why there was only one underlined passage, and perhaps also why there were all sorts of other mysterious pairs of numbers scribbled all over the

Meanwhile, though it seemed a bit much with everything else that was going on, I continued to attend my inane, pointless classes.
In Humanities we were still doing The Turbulent Sixties, working on the Peace Collage. There was this big pasteboard
“wall” on which you were supposed to glue things cut out from magazines that had to do with the sixties, or peace, or civil rights, or the women’s movement, or, well, just about anything at all, really. There was a lot of potential mischief afoot with all that glue, but I managed to avoid getting glued to anything for once.
In part, I believe, this had to do with the Paul Krebs
One of the reasons it had been possible to knock him down, and probably the main reason he had given up so
