Arnold Golightly
Well, this has certainly been a most entertaining evening.
Reverend Arnold Golightly was the vicar of a small English village until his death in 1926. Born in 1886, he was given up to a church-run orphanage not long after his birth, and was raised there. As an adult, he found a post as the vicar of a sleepy English village near Eddison Manor. Some time after his fortieth birthday, in 1926, his church suffered a break in--during which he discovered that he was not human... or, at least, not only human.
He was, in fact, half-Human and half-Vespiform, the illegitimate son of Lady Clemency Eddison and a Vespiform calling itself Christopher. The Vespiform side of his genetic makeup, dormant until then, asserted itself and its psychic bond to the Firestone. The nascent Vespiform used the Firestone to access the mind of Clemency Eddison; since she was reading a book by Agatha Christie at the time, its personality molded itself along the lines of an Agatha Christie plot.
Arnold was killed, in his Vespiform form, by Donna Noble, who tossed the Firestone into a lake. The psychic bond between a Vespiform and its Firestone was so strong that the Vespiform Arnold flew into the lake after it--and drowned, just as his father had drowned in the 1886 monsoons.
