Missing Links to the Culper Spy Ring?

Book excerpt: " ... I inherited Revolutionary War letters which various citizens had written. The main character is the obscure Rev. Andrew Eliot of Fairfield Connecticut which I hypothesize may have been an American Secret Agent facilitated in these endeavors by Aaron Burr's first cousin, Thaddeus Burr. Benjamin Tallmadge, Robert Townsend, Austin Roe and Caleb Brewster were known to have participated in the Culper Spy Ring informing General George Washington of the British troops whereabouts and supplies. Until now other members have not been identified ... read for yourself the evidence presented here with scanned letters and artifacts and the genealogy that illustrates how I am in possession of these fascinating historical records"--Preface.
