The Victorians were obsessed with doubles, whether
the literal evil twin brother of the doppelgänger popularised by E.TA. Hoffman,
Edgar Allan Poe, and Oscar Wilde or the figural pairing of the civilised and
the savage in Dr Jekyll and Mr Hyde, Edward Prendick and Dr Moreau, and Charles
Marlow and Mr Kurtz. Conan Doyle was no exception to the rule. Doubles appear
in two of his Sherlock Holmes stories, ‘The Final Problem’ (1893) and ‘The
Adventure of the Creeping Man’ (1923), in the pairing of Holmes and Professor Moriarty
and Professor Presbury and Presbury-on-serum respectively, and the fact that Dr
Watson never sees Moriarty raises the intriguing possibility that he is
actually a doppelgänger. Doyle also deployed doubling in his horror fiction,
most notably in ‘A Pastoral Horror’ (1890) – Father Verhagen and
diseased-Verhagen – and ‘The Terror of Blue John Gap’ (1910), both of which I
selected for Theaker’s Paperback Library’s
The
Conan Doyle Weirdbook.
‘The Terror of Blue John Gap’ is an epistolary novelette
of just over seven thousand words, which is divided into seven diary entries by
Dr James Hardcastle, from 17 April 1907 to 10 June 1907, bookended by a foreword
and a single-sentence conclusion by an implied author. Although Hardcastle is
introduced as a man of science, he was terminally ill with tuberculosis at the
time of the events chronicled and the story is replete with suggestions that he
is an unreliable narrator. The repeated reflections, allusions, and intimations
of mental illness are matched by a carefully constructed undermining of the
possibility of corroboration. Hardcastle thinks he hears, sees, and shoots a
blind, ‘bear-like’ beast taller and broader than an elephant and ten times the
size of the biggest bear, but all the reader knows for certain is that he
entered Blue John Gap mine, fell, and lost consciousness. Hardcastle first hears
about the beast from a young man named Armitage on 17 April, when he favours
prosaic explanations of missing sheep and a damaged wall. By 3 May, Armitage
has himself disappeared and Hardcastle leaps to the completely baseless
conclusion that the beast is responsible. Hardcastle’s shot either misses or
fails to draw blood and his vague description of his own wounds – concussion, a
broken arm, and two broken ribs – is ambiguous as to whether they were caused
by a swat from a gargantuan mole or a fall down a mine shaft. Finally, the
locals are quick to dissuade ‘adventurous gentlemen’ from descending on their
peaceful haven in the Derbyshire Dales and repair the gap to prevent any
further exploration.
I’m increasingly convinced that Doyle’s
achievement is similar if not identical to that of Henry James in The Turn
of the Screw (1898), where the interpretations of psychological and supernatural
horror are equally valid to the extent that the ambiguity is constitutive of
the work’s literary value. If the beast is an overgrown figment of Hardcastle’s
imagination, then it is likely the product of his unconscious and ‘The Terror
of Blue John Gap’ a psychological horror story. Hardcastle is exemplary of the
Victorian gentleman, a well-educated and well-mannered man of reason with a
steadfast moral compass, a propensity for bold action when provoked, and the
gender, class, and ecological prejudices of his time. As he narrates the
majority of the narrative, the reader becomes acquainted with both his actions
and his thoughts. The beast, in contrast, remains entirely enigmatic, with much
of its appearance left to the reader’s imagination and scant explanation of its
evolution, habitat, or behaviour. It is, in short, wholly Other to humanity in
general and Hardcastle in particular. If the beast is real, then the narrative
recalls the novels of one of Doyle’s contemporaries, H. Rider Haggard, whose
serial protagonist Allan Quartermain is the archetypal Great White Hunter.For Haggard and the majority of Victorians, nature
was simply a resource to be mastered, adapted, and exploited for humanity’s benefit,
notwithstanding the widespread acceptance of Charles Darwin’s theory of natural
selection. Yet Doyle’s perspective on the relation between Hardcastle and the
beast, whether mental or material, is much more sophisticated and explored with
a calculated literary artifice that employs two converging configurations.

First, he distances his readers from Hardcastle as
the narrative progresses, a cumulative effect achieved by the combination of repeated
references to his unreliability with an escalation of his obsession to uncover
the mystery of the mine, an investigation he is patently unfit to undertake. Hardcastle
is most unsympathetic in his determination that Armitage has fallen victim to the
beast, convincing himself that the beast has taken Armitage in order to justify
the satisfaction of his own desire to hunt and kill it. Second, Doyle invites readers
to empathise with the beast by means of the late revelation of its
vulnerability (blindness) and the even later speculation as to its origin
(earthly not infernal). The epistemic ambiguity is thus extended to the ethical
and the story closes with the question of whether our sympathies should lie
with the beast or with Hardcastle. The beast is the most complex of Doyle’s
doubles because in spite of representing the brutish, savage, and untamed
aspects of humanity, it is not presented as meriting approbation – like
diseased-Verhagen, Moriarty, and Presbury-on-serum. As such, the doubling of
Hardcastle and the beast is an instantiation of what Mark Bould refers to as
the environmental uncanny in The Anthropocene Unconscious: Climate Catastrophe Culture (2021): the recognition by human beings that they are
in the presence of nonhuman agency, which draws attention to the play of
identity and difference between human and nonhuman. Whether produced by
Hardcastle’s unconscious or by natural selection, the beast sheds light on the
relation between the human and the natural worlds.
It would be stretching credulity to categorise ‘The
Terror of Blue John Gap’ as eco-fiction – fiction that takes the integration
and interdependence of humanity and the environment as its subject – but
Doyle’s deployment of doubling in the novelette is distinct from the other
three examples I cited. Diseased-Verhagen is a serial killer, Moriarty an evil
genius, and Presbury-on-serum a rapist-in-waiting. The beast is neither
homicidal nor evil nor rapacious. While the zoocidal Hardcastle’s agency is
impaired by his obsession, the beast has sufficient control of its instincts to
refrain from making a meal of his unconscious body. That ‘awful moment when we
were face to face’ is likely to have been awful for each of the doubles, the
pair of which provide a reminder of the invisible ties among all living
species.
