79 – The Seventy-Ninth Card: A Tarot Thriller · By François R. Bonchamp
Seventy-eight states. A fixed grammar of gaze and angle. For 140 years, nobody gave you the specification. Until a man in Lambeth taped tracing paper over The Tower at 2:14 in the morning.
“Take down your own deck, any standard one—the design that has not changed since 1909. Put it on the table beside this page. Everything I tell you from here on, you can check with a ruler. If you can’t check it, don’t believe it. I did not.”

Empirical Verification · Rider-Waite-Smith (1909)
Every geometric vector in 79 is drawn from Pamela Colman Smith’s original 1909 line work. Select a card below and overlay the tracing paper.

SPECIFICATION TEST 01 // CARD XVI: THE TOWER
“Everyone knows there are twenty-two teardrop flames (yods) hanging in the black sky—one for each of the Major Arcana. Nobody ever puts the card down on a table and draws a vertical line through the exact center of the tower.”
“12 on the left. 10 on the right. The card is weighted. People have been looking at what falls for a century. They should look at who is watching it fall.”

SPECIFICATION TEST 02 // CARD I: THE MAGICIAN
“The wand leans 3° left of vertical. The pointing forefinger descends at 33° to the right. Draw a straight line connecting the tip of the wand to the tip of the finger.”
“At 36° off the vertical, the line passes straight through his face, just left of the bridge of the nose—and exits the right border at exactly 0.66 of the card’s height. Lay that same line over Card II (The High Priestess): it drops straight onto the letter ‘B’ on the black pillar and hits the tip of the crescent moon at her feet.”

SPECIFICATION TEST 03 // CARD 0: THE FOOL
“Every book tells you the Fool gazes up at the sun, unaware of the cliff. Press a ruler to the screen.”
“The sun is at the upper right. His profile points up and to the left at 22° to 35°. The angle between his gaze and the sun is 120 degrees. He is looking away from the very thing he holds the white rose toward. An inconsistency is either a mistake or a decision.”
The Premise
Cormac Corrigan doesn’t believe in luck, stars, or crystals. He writes the software that sits underneath the money in the City of London—the layer where one bank tells another bank it owes it forty million pounds before the close. He is paid to distrust everything and to find the three places in a four-hundred-page specification where the text contradicts itself.
When he starts measuring the gaze vectors of the 1909 tarot deck for strangers on an internet forum under the handle fsm_78, he catches the attention of Oculus_1909—an old man who uses the exact same geometry to predict Treasury gilt yields to the basis point and boardroom votes to the minute.
Then two men in blue jackets knock on Oculus’s door at 2:40 AM, claiming a gas leak. Days later, they are standing on Cormac’s landing in Deptford.
On the run across London’s railway arches, narrowboats, and the bleak waste of Rannoch Moor—alongside Delphine Okafor, an art historian hunting the lost proofs of Pamela Colman Smith, and Tamsin Lyle, a synesthetic piano tuner who can hear when a room or a network is thirty cents flat—Cormac uncovers the secret of St Aldhelm’s College:
For 140 years, a tiny Oxford elite has been taught “The Reading of the Pack.” They do not predict the future. They predict each other. Seated in banks, courts, and Whitehall ministries, they look at the same thirty-three-card grid in their heads and arrive, without a single phone call or order, at the exact same decision.
It is a machine made entirely of people. And Pamela Colman Smith left a single, hidden flaw inside it to break it open.
Acoustic Motif · Equal Temperament
“Two things that disagree, until they don’t. A piano is wrong on purpose in every note you play—a small lie everyone has agreed to, so that two people who have never met can play the same piece at the same time. What if someone tuned a society the exact same way?”
The Playable Appendix · St Aldhelm’s Common Room
Included in full at the back of the book: The Reading of the Pack—the complete, playable 1909 coordinate system and the full 78-card gaze and attribution table.
Reduce every card to its digit (1–9) and zodiac modality. A card in its own column and row is a Host. A Square where no card stands at home means only one thing: The Reader is looking at himself.
Track the 8 directional vectors of every pair of eyes (L, R, U, D, UL, UR, DL, DR). Count the Witnesses (OUT) looking straight at you. Find the Pockets (MUTUAL) where two cards look only at each other and the Pack cannot interfere.
Every standard ever made has a place left open on purpose, against the day when the standard must be given up. In this book, Chapter VIII is left blank for the person sitting in the 79th place: You.
Two Columns · One System
PILLAR B // BOAZ
PILLAR J // JACHIN
There is a place below the Ground, at the foot of the table, where you are sitting. No card is laid there. Do not leave it out of your reckoning. It is the most important place in the Square.
