Summary of the Case
In December 1913, a sensational scandal broke in Monticello, Sullivan County, New York, following the sudden death of former county prosecutor and lawyer Melvin H. Couch. Upon Couch's death from a ruptured aorta in his law office, authorities discovered that Adelaide Mary Branch (1873–1948), an educated former teacher and traveling book agent from the Cooperstown area, had been living secretly for three years (1910–1913) in a small partitioned room off his office. Branch referred to herself as his "heart wife," tending to his declining health in near-total isolation.
The case sparked nationwide -- even international -- media coverage. Following Couch's death, Branch was briefly held in the Sullivan County Jail, where prominent Progressive Era activists—including author Upton Sinclair, Mary Craig Sinclair, and Dr. James P. Warbasse—intervened to protect her from press exploitation and asylum commitment. Sinclair later chronicled her story in his 1919 book The Brass Check. In 1914 without ever publicly revealing her new name. Sinclair severely criticized the manner in which the Monticello incident was reported by the yellow press.
After Branch escaped from Monticello and spent a month in a rest home on Long Island, she had by eight months of isolation in Hamilton, Bermuda (a portion of which she spent with the Sinclairs) in order to build a new sense of herself, complete with a new identity, and she lived her life as independently as she chose. Branch assumed the identity of "Mary Douglas" -- the surname came from her family line -- and lived in New York and Washington, D.C. until her death in 1948.
Prior to the present biography by Tom Rue, the rest of Adelaide's life story was unknown to historians. The Hidden Woman: How Adelaide Branch Became Mary Douglas is slated for release in 2027.
