Academics who have worked on Arthur Conan Doyle will recognize two types of articles that they are frequently asked to review: the first identifies an obscure topic from the Sherlock Holmes stories and pursues it in excruciating detail (imagine an article titled “Alpinestocks vs Alpine-Stocks: The Case of the Vanishing Hyphen”); the second operates in an entirely different discipline but uses the figure of Holmes to structure its argument (perhaps “‘Some Ecstatic Dream’: Sherlock Holmes and REM Sleep Cycles”). The former usually totters along the ill-defined border between Holmesiana (the half-satirical, half-earnest pursuit of canonical truths within the Holmes stories) and conventional literary criticism. The latter, an easy desk reject for scientific journals without the Holmesian framing, can be sanguinely passed on to a humanities scholar to fire the necessary bolt to the temple. The proliferation of both types illustrates the wide variety of truth-claims for which Holmes’s testimony can be summoned. Brian McCuskey’s How Sherlock Pulled the Trick: Spiritualism and the Pseudoscientific Method identifies and analyzes a series of public debates and controversies (political, religious, and academic) where Sherlock Holmes or the vaunted Holmesian method was generally invoked by all sides as a guarantor of their correctness. The examples are mostly drawn from the career and afterlife of Conan Doyle himself. McCuskey explores Holmes’s method in some detail, mostly offering a useful summary of work on the subject by the likes of Stephen Knight, Ronald R. Thomas, Thomas Sebeok, and Michael Saler. He argues, in broad terms, that the central “paradox” identified in Conan Doyle’s life by many writers and biographers—how could he create the great rationalist detective and also believe in spiritualism and fairies?—is a false dichotomy (46). While Holmes avowedly excluded the supernatural from his worldview, his mode of reasoning was entirely specious, unfalsifiable, and purposefully riddled with gaps that could be supplemented with leaps of faith, so-called common sense, nonsense, errata, confirmation bias, or ordinary prejudice. In short: you can find a Holmes quote to support any imaginable proposition whether profound, trivial, or unhinged. [End Page 687] Yet, since Holmes’s first appearance in A Study in Scarlet (1887), he has been deployed in a bewildering array of debates. McCuskey’s chapters, though they do add up to an overarching argument, read more naturally as a series of smaller case studies. Chapter 1 examines a snapshot of religious debates around eyewitness testimony, textual reliability, and the limits of infallibility in 1887. Did the Reverend Malcolm MacColl really see the corpse of an impaled Christian martyr on the banks of the Sava River or was it a “large bundle of drying haricot beans” (15)? The terms of this debate, christened “What the Canons Saw” in The Times (1788–present), “seemed almost to summon” Holmes into being according to McCuskey (16, 17). This tendentious phraseology captures the book’s limitations but also some of its self-aware charm. McCuskey has written a book-length deconstruction of a purely fictional mode of reasoning that was never intended to be externally consistent. He occasionally chastises himself for this foolishness, belatedly and playfully pulling his own methodology into his critique. Other chapters examine the genesis and epistemic structure of Conan Doyle’s spiritualist beliefs, his career as a proselytizer and public debater, the growth of Sherlock Holmes fandom, the constructivist theory wars of the 1980s, and the character’s role in online conspiracy theories pertaining to 9/11 and post-Trump American politics. So how did Sherlock pull the trick and convince generations of readers that his method of crime solving was replicable in their everyday lives? How could the same character’s words be used in self-justification by 9/11 truthers and newspaper fact-checkers, QAnon devotees and august professors, evolutionary biologists and the Intelligent Design movement? The answer, of course, is that there is no Holmesian method, just a series of pleasingly-phrased, quotable...
