There were no sons, a fact that was noted in the society pages with the particular mixture of sympathy and satisfaction that attended such failures of dynastic planning.
Edmund’s business interests would pass eventually to his sons-in-law, assuming he could find men willing to marry into a family that had produced only daughters.
The daughters themselves were, by all accounts, remarkable.
Charlotte was described as brilliant, a voracious reader who had mastered Latin and Greek by the age of 16, and who had expressed a desire to attend university, a desire that her father had dismissed as unsuitable for a woman of her station.
Beatatrice was musical, a pianist of considerable talent, who had performed at charity events and private gatherings throughout the city.
Louisa was artistic, filling sketchbooks with drawings of plants and animals that she studied in the gardens surrounding the family home.
And Adelaide, the youngest, was described simply as strange.
The word appeared again and again in the documents I uncovered, applied to Adelaide with a consistency that suggested it was not merely a casual observation, but a defining characteristic recognized by everyone who encountered her.
She was strange.
She was peculiar.
She was not like other children.
The specifics of her strangeness varied depending on the source.
Some described her as unnervingly silent, others as prone to speaking in ways that made no sense, others as possessing knowledge that she should not have been able to possess.
One letter written by a neighbor to a relative in Boston described Adelaide as having eyes that seemed to look through you rather than at you, as though she was seeing something behind your face that you yourself could not see.
And there was the matter of her hand.
Adelaide Blackwood had been born with only four fingers on her left hand, the smallest finger absent, the hand otherwise normal in appearance and function.
This was not in itself particularly unusual.
Congenital abnormalities of the hand were common enough in that era, and families of means typically concealed such imperfections with gloves or careful positioning in photographs.
What was unusual was the way Adelaide’s family spoke about her hand, or rather the way they did not speak about it, as though the missing finger were not merely a physical characteristic, but a mark of something else, something that could not be named or acknowledged.
The photograph I had purchased showed Adelaide with her left hand clearly visible, the four fingers resting on the velvet chair, uncloded and unconcealed.
This was itself remarkable, a violation of the conventions that governed how such imperfections were presented in formal portraits.
But it was the shadow that made the image truly disturbing.
The shadow that showed five fingers where only four existed, the shadow that suggested Adelaide was casting the image of a hand that was not her own.
I became obsessed with understanding what I was seeing.
I consulted experts in Victorian photography, specialists in the chemistry of development and preservation, historians of optical illusions and visual perception.
Most of them dismissed the anomaly as an artifact, a trick of light and exposure and the degradation of the photographic materials over time.
One suggested that the shadow might have been created by a double exposure, a second image accidentally superimposed on the first during the development process.
Another proposed that someone had manipulated the photograph after it was taken, adding or altering the shadow for reasons that could only be guessed at.
None of these explanations satisfied me.
The shadow was too precise, too clearly defined, too obviously intentional to be an accident.
