Somewhere between the mythology and the muddy bottom of a swimming pool, Brian Jones left a paper trail nobody knew existed. A cache of previously unseen letters, discovered tucked inside a set of drawers, is now pointing toward an undocumented love affair between the Rolling Stones founder and a London shopgirl — a romance that, if the correspondence bears out, slipped entirely past the biographers.

The letters, whose contents hint at a sustained and affectionate relationship, are being described by those familiar with the find as historically significant. Jones, who co-founded the Stones in 1962 and was ousted from the band seven years later, died at 27 in July 1969, weeks after his dismissal. His personal life has been exhaustively catalogued in the decades since — which is part of what makes an undocumented entanglement newsworthy in rock-history terms.

The identity of the shopgirl has not been publicly confirmed. Whether she is traceable, living, or already known to Jones's inner circle remains unclear ahead of any formal authentication process.

What is clear is that the auction market for Rolling Stones ephemera runs hot. Handwritten letters from the band's founding era — particularly material tied to Jones, whose short life and outsized influence give him a near-mythic status among collectors — routinely exceed pre-sale estimates. The current cache is expected to fetch thousands of pounds when it goes under the hammer, with final estimates pending appraisal.

No sale date has been confirmed as of the time of filing.
