Archibald Angelchrist

Professor Archibald Angelchrist was a senior member of the Secret Service (COMIC: The Undying) as well as a good friend and occasional companion of Iris Wildthyme. (PROSE: Iris at the V&A)

Secret Service
In his time working for the secret service, Angelchrist had many encounters with alien life including: strange tentacled things that clambered out of the Thames, people possessed by an apparently extraterrestrial virus that drove them murderously insane, and ancient entities awoken from their tombs beneath Edinburgh. (PROSE: Paradox Lost)

Adventures with Newbury and Hobbes
In 1902, Angelchrist tracked down the Maharajah's missing Star, an artefact with apparent unimaginable value, with the help of Maurice Newbury, Veronica Hobbes and Charles Bainbridge. The group traced the Star's whereabouts to a criminal gang of smugglers and pirates who were operating in a warehouse out of the London Docks. The warehouse was guarded by a carnivorous bird and several reanimated pygmies, but the group were able to defeat them and get to the cabinet where the Star and the other treasure was held. The group turned the treasure over to the Crown, but it was agreed that Angelchrist would keep the Star in his own personal protection after they discovered that the Star was a worthless teacup and had more value being left a mystery. (PROSE: The Maharajah's Star)

In 1903, Angelchrist summoned Newbury, Hobbes and Bainbridge to his country seat in Oxfordshire, which he had obtained earlier in the year from his late uncle, in order to inspect a creature that his men had found while dredging the lake. It was decided that the corpse would be taken to London and inspected by Dr John Farrowdene. Farrowdene confirmed that the creature was a mutated human and indicated that Dr Aubrey Knox was behind the creature's creation. Angelchrist accompanied the trio to inspect Knox's laboratory and attempted to save Veronica's life from another mutant creature by shooting it with his pistol. They were taken prisoner by more creatures, but eventually managed to escape. (COMIC: The Undying)

Angelchrist retried from the secret service around 1905. Five years later in 1910 he began to investigate The Squall and helped the Eleventh Doctor to defeat them. (PROSE: Paradox Lost)

In 1911, Angelchrist helped Iris and Panda defeat the Piscotorians in hand-to-hand combat. (PROSE: Iris at the V&A)

In 1915, Newbury introduced Angelchrist to Sherlock Holmes and John Watson. (PROSE: The Spirit Box)

In 1920, the Doctor, Amy and Rory returned with Arven, who had been given a new body, and left him to live with Angelchrist. (PROSE: Paradox Lost)

In the 1930s, Angelchrist received a letter from Iris concerning her encounter with Marlene Dietrich in 1977 Berlin. The letter was later included in The Collected Letters, 1918 - 1938. (PROSE: Low/Profile)

When the criminal Zenith threatened the prime minister of Great Britain, Angelchrist was asked to track him down. (PROSE: The Albino's Shadow)

Behind the scenes
Although Angelchrist's first appearance in a commercial work was in Paradox Lost (for which he was created), he made an earlier appearance in print in the charity short story The Maharajah's Star, later re-relased in a more official context in The Casebook of Newbury & Hobbes. As we only consider commercial releases valid, this Wiki considers the character to have debuted in Paradox Lost, serendipitously fitting the character's genesis, though not his publication history.

Beyond his crossover appearances in Mann's original series Newbury & Hobbes, Angelchrist also featured under license from his creator in The Albino's Shadow in the 2012 Obverse Quarterly collection Zenith Lives!.
