It was his grandmother’s final wish, formalised in her will:
And to Mungo, I bequeath the contents of my safety deposit box, provided he keeps his word to me and marries within the year.
Mungo, the eldest son of a duke and in his thirties, hadn’t shown interest in marriage, although often seen with various celebrity women but now speculation mounted.
A year after his grandmother’s funeral, at a private ceremony, Mungo married his secret commoner lover of many years. The ring, his grandmother’s, had been in the lockbox.
Mungo proudly introduced his new husband to the family soon after.
