The Investigation
A cipher embedded in
the founding letters
of New England
In the 1640s, John Winthrop — first governor of Massachusetts Bay Colony, the man who gave America the phrase "city upon a hill" — encoded a set of directions in his private correspondence with his son. The directions describe a place. The place is in Massachusetts. Whatever he left there, he wrote, was left "where another age might find it."
In 1882, a meticulous archivist named Nathanael Edes found the cipher. He traveled to the sites. He published a carefully arranged scholarly edition of the letters and said, in the most precise and deniable language available to a 19th-century scholar, that he believed the thing was still there. Then he went home and kept thinking about it until he died.
In 2021, a historian named Miriam Appleton found Edes's annotated working copy in a box of books in Jamaica Plain. She has spent three years following both men. The edition is nearly ready.
1630
Winthrop arrives in Massachusetts
The Arbella fleet lands. The Massachusetts Bay Colony begins. Winthrop governs for twelve of its first twenty years.
1644
The cipher letters are written
Autumn. Three letters from the governor to his son John Jr. in Ipswich. The postscripts carry directions to a place the Nipmuc had described as a place of keeping. Not buried. Set.
1649
Winthrop dies
March 26th. The letters survive. John Jr. — alchemist, governor of Connecticut, Fellow of the Royal Society — never returns to retrieve what his father left.
1882
Nathanael Edes begins his research
Archivist at the Massachusetts Historical Society. He finds the cipher. He visits the sites. He cannot bring himself to say plainly what he has found.
1887
Edes publishes his edition
Privately printed. The letters arranged in an order that is not chronological and has never been explained. The arrangement is the first key.
1895
Edes dies. The working copy disappears.
October. He leaves the annotated copy at the Brandegee Estate library. Two people find it. They read it together at night. They understand something Edes could not quite reach.
~1915
Fire in Jamaica Plain
The books survive. The eleven matching ledgers — one of them heavier than the rest — pass through several hands, unexamined.
2021
Miriam finds the seventh ledger
Spring. A box of books from a Jamaica Plain bookshop. The seventh ledger is heavier than the others. Inside it: the working copy, the annotations, and three sheets of paper in two hands she does not recognize.
2026
The investigation becomes public
The first coin is in the field. The edition is in preparation. The cipher is open to anyone willing to read carefully enough.
2027
The Winthrop Cipher: A Scholarly Edition published
All clues are in the letters. The book is the map.
2030
Resolution
The 400th anniversary of Winthrop's arrival. The final solution is confirmed. The cipher closes.
The Chain of Custody
1640s
John Winthrop
Encodes directions in letters to his son. Leaves something in the landscape. Trusts another age.
1882–1895
Nathanael Edes
Finds the cipher. Travels to the sites. Publishes a carefully arranged edition. Dies having said almost nothing to anyone.
1895–1915
The Second Readers
Two people who found the book after Edes. Read it together at night. Understood something. Could not act on it.
2021–
Miriam Appleton
Found the working copy. Found the other papers inside it. Has spent three years following all of them.
The letters are real. The ground they describe is real. Something was placed in that ground nearly four centuries ago, and it is still there.
— Dr. Miriam Appleton, Editorial Introduction, 2027
How It Works
I
The Book
A scholarly edition of Winthrop's correspondence — real letters woven with invented ones, arranged in an order that rewards obsessive attention. There is no hidden code. There is no invisible ink. The cipher is the correspondence itself, read by someone who understands what Winthrop was doing when he wrote it.
II
The Coins
Ten gold coins hidden across properties managed by the Trustees of Reservations — Massachusetts' oldest land trust. Each coin found releases a new clue. Each coin carries $10,000 in gold value plus a $20,000 award for verified finders. The reverse reads: Left where another age might find it.
III
The Solution
The ten coins, understood together, point to something else. The grand treasure — approximately one million dollars — goes to the first solver who submits a complete and correct solution. The solution is not found by digging. It is found by understanding.
A Taste of the Cipher
The footnote
Edes left behind
On page forty-seven of The Ledger and the Lord — Miriam's second book, published in 2019 — there is a footnote. It concerns three letters written by Winthrop to his son in the autumn of 1644. It describes an annotation Edes made in his working copy: a single word, underlined once, with no other comment.
She set it down in print in 2019 because it interested her. She did not yet know what it meant. She found the working copy two years later. The word was still there, in Edes's compressed pencil hand, exactly as she had described it.
This is what the cipher looks like. Not codes. Not ciphers in the mechanical sense. Just careful men and women reading the same documents across a century and a half, each one getting slightly closer to what Winthrop meant when he wrote, in October of 1644, that the thing was not buried but set, and that the distinction seemed to matter.
"...I note this here because Edes, in his 1887 edition, gives the dates without conversion and without comment — an editorial decision that, considered alongside his non-chronological arrangement of the letters as a whole, I find it difficult not to regard as deliberate. What Edes made of these three letters in particular I cannot determine with certainty. His working copy, which I have examined, contains a single annotation against the passage in the second letter describing the ground 'between the stone I have described and the water lying to the east of it'..."
Edes's annotation, working copy, c. 1889–1895:
The word good, underlined once.
No other comment.
Miriam's note: "I have thought about that word at some length. I set it down here for the reader who may find it more legible than I have."
The Landscape · 1630 – Present
The ground is
still there
Winthrop described it. Edes annotated his map. The coordinates are in the letters. Massachusetts has not moved.
The Cipher
Hidden in Plain Sight
There is no invisible ink. No hidden compartment. The cipher is the correspondence itself — read by someone who understands what Winthrop was doing when he wrote it, and what Edes was doing when he arranged it.
The Calendar
A Different Way of Counting
The Puritans began their year in March. "The second day of the third month" is not what a modern reader assumes. The dates in the letters are directions. You need to know how to read the clock.
The Arrangement
Not Chronological
Edes arranged the letters in an order that is not chronological and has never been explained. Miriam has spent three years on this. The arrangement is not arbitrary. It is the first key.
The Second Stone
The One That Matters
"The stone he means is not the stone the other man means. Two stones. The second is the one." Written in a hand Miriam cannot identify, found folded inside the working copy. The second readers got further than Edes did.
2030
The 400th Anniversary · Massachusetts Bay Colony
In 2030, Massachusetts marks four hundred years since Winthrop's fleet arrived in the harbor. The cipher is designed to resolve in that year — its final chapter timed to the moment the Commonwealth looks back at its beginning.
The Edition · 2027
