When Cromwell ran it by his postcard deciphering department, he realised his mistake. It was from Truella, not Frella. A second postcard from Truella provided more information.
Truella had been at the fair in Ireland when she sent the postcard. There had been a Tudor Camphor Magic stall that she was drawn to, partly because of Frella’s mysterious camphor chest, but not just because of that. Her encounter with Lovelace Maraschal and his souvenirs and 16th century postcards and paraphernalia was a fleeting obsession.
Five hundred years later the staff at the National Archives would roll their eyes at the sheer volume of postcards from Truella there were in the Thomas Cromwell collections.
