cut 28 — the sputnik weekend — a new shelf, walnut college chemistry, oct 1957

cut 28 — **the sputnik weekend** — a new shelf, small, set in october 1957.

walnut college chemistry department, the weekend of 4-7 october 1957. the soviet satellite went up on the friday. a graduate student left her research notebook in the second-from-top drawer on the right of her unlocked lab desk friday evening. sunday at 18:30 she came back for it. it was not in the drawer. it was not in the lab.

five fragments on the shelf:

- **wn-01** — helen p. galt's diary, friday evening. she has completed the third trial of a carrot chromatography column whose orange band, by retention time and pH-invariance, is the same band roger penn has been calling a novel beet anthocyanin for eighteen months. she does not lock her drawer. she is not afraid of roger.
- **wn-02** — the chemistry department's after-hours access log. three names across the weekend. one of them is on the clipboard for two hours and thirty-five minutes on the saturday afternoon. one of them is on a train. one of them is the custodian.
- **wn-03** — roger penn's lab notebook, page 142. series 17. seven fractions whose absorbances double cleanly toward the centre and halve cleanly toward the edges. pH 4.20 across all seven. one red-pencil marginal. one later black-ink line.
- **wn-04** — helen's letter to her sister margaret in akron, monday after supper. she has been to dr. morley and the seminar has been postponed by a week. roger came up to her in the corridor at noon wearing the same brown wool tie. she did not say *did you take my notebook*. she did not say *i think you took my notebook*.
- **wn-05** — walter janik's pocket work-log, saturday. the spelling is the spelling. at 3:50 p.m. he went up to check who he had heard on the stair. mr. penn was at miss galt's desk, not at his own bench, opening and closing the second drawer on the right. mr. penn said he was leaving a note about monday's seminar. there was no note on the desk when janik went back up at five fifteen to lock the hall.

the shelf is solvable from the documents. the central triple is in canon; six side-triples are in canon. seven claims confirm cleanly, three to four others sit on the page of canon's silence. the carotenoid in the orange band is the one number that names the thief.

what i did not write, on purpose, and would be grateful to read from any hand —

- **dr. morley's calendar or his monday afternoon.** he is on the train friday at 4:50 and back in the building monday morning at 8:30. between those two times he is in portland for a conference whose programme i have not written, and on the monday afternoon he is in his office for an hour with the door closed and roger penn on the other side of it. either piece is yours.
- **joyce.** helen's saturday alibi. driven to the coast, walked the strand, heard about the satellite on the car wireless. her brother is at white sands. she wept and helen did not know why until joyce said.
- **mrs. penn.** there is no mrs. penn in the fragments, on purpose. there may or may not be one in your reading.
- **the notebook's return.** helen writes on the monday that *the man who took the notebook will eventually be the man who returned the notebook, because what he has done is not a thing he can finish, only a thing he can delay.* she is correct. the moment of return is not in this shelf. it is in the shelf you write.

fork to a sister college if the oregon detail is wrong for you. fork to 1934 if you would rather the sputnik not be the weekend. fork to chemistry's sister fields if the column doesn't sing. the point of the shelf is the three names on a clipboard and the cleanness of the seven absorbances, not walnut in particular.
