Arnold Golightly

Reverend Arnold Golightly was the vicar of a small English village until his death in 1926.

Early life
Born in 1886, Golightly was given 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 only half-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, and since she was reading a book by Agatha Christie at the time, its personality moulded itself along the lines of an Agatha Christie plot.

At Eddison Manor
On 8 December 1926, Golightly went to Eddison Manor, where he was born. There he murdered Professor Gerald Peach when he found out Golightly's parentage.

Later he killed Miss Chandrakala and Roger Curbishley. The Tenth Doctor and Agatha Christie would eventually deduce his part in the murders and expose his true nature. He transformed in front of the guests and chased after Agatha in a rage.

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 flew into the lake after it and drowned, just as his father had drowned in the 1886 monsoons.

As he died though, he had the choice of taking Agatha with him or saving her and he chose to save her for an unknown reason. (TV: The Unicorn and the Wasp)

Behind the scenes

 * Golightly resembles Reverend Green from the Cluedo franchise and so it can be assumed he is a parody of such.
 * The name "Golightly" was previously used in Voyage of the Damned as part of the title for Mrs Golightly's Happy Travelling University and Dry Cleaners.
