Perimeter answers from clues clockwise from 1ac were: outing, kismet, tonnes, manger, center, teeter, impart, oaring. Letters falling in the indicated cells, using one twice, could then be arranged to form “Cogito ergo sum”, leading to “René Descartes” to form the substitution code. Changing, in shaded cells, the letters of the phrase to the equivalent in the name produced new words in the perimeter. The letter used twice was O which may be seen to code to E twice in the key and so all 12 distinct code pairings were used, the extra making up the “baker’s dozen”.
