Strong Poison by Dorothy L. Sayers

Originally Published 1930
Lord Peter Wimsey #6
Preceded by The Unpleasantness at the Bellona Club
Followed by The Five Red Herrings

Lord Peter Wimsey comes to the trial of Harriet Vane for a glimpse at one of the most engaging murder cases London has seen in years. Unfortunately for the detective, the crime’s details are distractingly salacious, and there is little doubt that the woman will be found guilty. A slightly popular mystery novelist, she stands accused of poisoning her fiancé, a literary author and well-known advocate of free love. Over the course of a few weeks, she bought strychnine, prussic acid, and arsenic, and when her lover died the police found enough poison in his veins to kill a horse. But as Lord Peter watches Harriet in the dock, he begins to doubt her guilt—and to fall in love.
As Harriet awaits the hangman, Lord Peter races to prove her innocence, hoping that for the first time in his life, love will triumph over death.

Revisiting the Lord Peter Wimsey mysteries in order has been quite instructive for me as I have come to appreciate the evolution of the character. In my review of his first adventure, Whose Body?, I noted that while the affectations and core personality traits were all basically there, the character often read as flippant and tiresome. Those traits were gradually toned down in the subsequent stories as it was made clearer that this personality has been, at least to some extent, cultivated to make him appear less threatening.

The previous story in the series, The Unpleasantness at the Bellona Club, had presented readers with a more sharply defined and sympathetic version of the character. While he was still capable of flippant witticisms, there we saw him act out of care for another, fighting on their behalf rather than just engaging in criminology as a hobby. This book takes that idea one step further, seeing him become involved to save a young woman he has fallen in love with from the gallows.

That character is, of course, the mystery novelist Harriet Vane who will go on in subsequent novels to become his partner in detection. This change significantly alters the tone and themes of the series in those books but that of course will be a discussion for later reviews. Here she plays only a limited role, briefly appearing in just a couple of chapters and to provide inspiration for Lord Peter’s efforts to uncover the truth.

The reason for this is that at the start of the novel Harriet is on trial for murder. She is suspected of having poisoned her former lover, the novelist Philip Boyes, using arsenic. Her supposed motive is that she had agreed to live with him without being married having been convinced of his opposition to the institution, only for him to subsequently offer her marriage after all. She clearly felt angry and betrayed, leaving him.

The problem for Harriet is that she had been identified buying arsenic, apparently to test to see how easily it could be procured for a future novel and no one else seems to have a clear motive. Lord Peter refuses to believe her guilty, not based on any evidence but based on his instinct and strength of feeling about her and tells her that he will work on her behalf to find evidence to acquit her, telling her that he wants to marry her when it is all over.

This initial point of attraction is, for me, the weakest part of the story as I think Peter’s attraction to her has to be quite superficial. I think it could be fairly categorized as an example of the love at first sight trope as he wants to marry her before he has ever spoken with her himself. Sayers even seems to draw a parallel between Peter and other men, noting that Harriet has already received a number of other offers of marriage since being arrested. Still, I think the reader can infer reasons for that attraction based on his perception of her character and smartly the author does not give us the gratification of a quick acceptance of his affections.

While the initial attraction may be superficial, I love the way these characters verbally tease and play with each other. Some of those moments are quite sharp and witty – a favorite exchange comes when Harriet suggests that he is overlooking that she has had a lover to which he replies that he has had several himself and can ‘produce quite good testimonials’. These moments have a charm and energy to them that lifts the piece and I enjoy any moments the pair are together.

Which helps make up a little for the rest of the book. As appealing as Lord Peter’s flirtations with Harriet are, I find the mystery plotline here to be rather underwhelming.

Part of the problem I have with this is that the killer’s identity is quite clear from early on in the novel. This is not because there is much reason for the investigation to settle on him but rather because there is simply no other suspect. Now, I’m the last person to complain about knowing the killer’s identity but if you are going to make their identity clear then you might as well commit to the inverted form properly as in Unnatural Death and either give us greater access to their thoughts or more directly establish a relationship between them and the sleuth.

A game of cat and mouse is only really fun if both parties are aware that they are playing. While there are a couple of moments where criminal and sleuth interact, there is not much back and forth or manipulation to be had here. Instead a lot of time is spent in what I consider filler material, with characters working to secretly obtain information. Those sequences are often quite memorable and entertaining such as a very clever seance sequence or the visit to a rather unorthodox Christian fellowship meeting but these passages move very slowly and little of what we learn will surprise.

In addition to learning the killer’s identity, the reader will also need to detect a motive and understand how they did it. The killer’s motive is, once again, relatively straightforward though I appreciate it does convincingly explain why the killer needs to act at that precise moment. A problem is that, as with proving the killer’s identity, the process by which we learn the killer’s motive feels strung out. Another is that surely almost everything that gets found would be inadmissable because of the way in which the information is gained (though perhaps the law on that point was very different in Britain in the early 30s).

Which brings me, finally, to the means by which it is managed. This is perhaps the book’s most creative idea, though it probably wouldn’t work in reality. While I think some parts are basically not guessable because they rely on prior knoweldge, the reader should be able to work out the significance of some key bits of information and start to piece those ideas together to at least give a general idea of how the poison must have been delivered. Those ideas are clever and exciting. I can certainly understand how it might work for others.

So overall then I found this to be rather a mixed bag (and that’s not even touching on the rather uncomfortable paragraphs where characters discuss Jewish bankers). The good bits of the story are both successful and interesting but I struggled with how bland the novel’s villain felt and had problems with the general pacing of the tale. Sayers was certainly capable of better and I think, were Harriet not introduced in this story, it would not be remembered anywhere near so fondly.

The Verdict: This successfully introduced some elements that would benefit later stories. Unfortunately the case feels padded, unremarkable and overrated.

This counts towards the Vintage Scattegories challenge’s Murderous Methods category as a Golden Age read.

Further Reading

Curious whether the method used here would work? Several years ago The Guardian published a story discussing it, basically saying that while the science was credible in 1930s understanding, it doesn’t stand up today. Be warned that the article does give the solution away so read at your own risk.

Nick at the Grandest Game in the World considers this one of Sayers’ best, appreciating the witty writing and the inclusion of Miss Climpson who, yes, is ‘as splendid as ever’.

  1. Thanks for writing about this book. I share fond memories of it, for just the reasons you mention.

    I remember reading an article, in one of the anthologies of writing about mystery, that examined the scientific plausibility of tricky murder methods in several books, and while the author determined that most of them wouldn’t stand up, the one in this book would work. As you suggest, this may be based on now-outdated information. (I’ll try to track the book down this afternoon.)

    This is also one of the books in which Sayers’s own experiences as a woman are most clearly drawn on for fictional purposes. (I know there’s also Gaudy Night; but scholarship and integrity are also primary themes there.) There are Miss Climpson’s remarks to the effect that anyone longing for the “good old days” must be male, as traveling and booking a hotel by oneself used to be a humiliating experience for an unaccompanied woman. But more centrally to the story, the whole business of being persuaded to live unmarried with a man who “was opposed on principle to marriage,” and then seeing him betray those principles, was based on her affair with the writer John Cournos. He did indeed persuade her to do that, then after they broke up relocated to the US and got married, leaving her feeling a fool for believing his so-called principles.

    1. I really like those aspects of the book as well. I share your appreciation for the social comment within the book as well, particularly given – as you point out – that some of it reflects her own life experiences and so feels particularly sincere.

      I certainly thought that Sayers conveys the reasons why Vane would have been so upset about the marriage test very well. In fact one of the most striking aspects of this book is that Harriet is defined so well given how little she directly appears. She is immediately likeable and I really like the relationship that begins to form with Peter. It is sometimes teasing and flirtatious but also truly sincere.

      Similarly I continue to really appreciate Miss Climpson. This book shows her to be smart and resourceful and she and Miss Murchison get many of the most exciting moments in the story!

      My understanding is that the principle of the technique is not flawed but rather that the poison selected here does not work quite as described. That is hardly Sayers’ fault – it’s just unfortunate.

      1. Thank you for the kind words. So many seem to be down on Harriet, but I think she elevates any scenes in which she appears. Also, I’ve never seen any mention anywhere that the opening sequence of the Margaret-Rutherford-as-Miss-Marple movie “Murder Most Foul” seems to be lifted from (or suggested by, if one prefers) the opening chapter of Strong Poison: The hung jury because of one stubbornly principled old lady. It’s not in Christie!

        I’ve tracked down the article I was remembering: “Inquest on Detective Stories” by R. Philmore (1938), in the collection The Art of the Mystery Story, ed. Haycraft (1946). Philmore considers Unnatural Death, Strong Poison, Behold Here’s Poison, The Red Widow Murders, and No Friendly Drop. He quotes a medical expert on each of these, with citations, and concludes, “All these five murderers sailed near the wind; all were lucky, in varying degrees, to kill their victims.” But in fact Strong Poison comes off the best of the five… at least in 1938.

      2. Oh no, I am definitely in favor of Harriet in general (and the changes she brings about in the characterization of Peter, though I think it really extends the work already underway in the previous book). In fact, when I was dating my now-wife we used to have matching LPW and HV-themed usericons and usernames on our various messenger platforms and Livejournal.

        Thanks for the reference – it sounds like a really interesting read. I have a couple of those stories referenced left to read but I will have to check it out when I have done that. Thank you!

      3. I’m glad to have been able to provide the reference. The whole book is well worth tracking down if you don’t already know it. It’s a fun read and a good mid-century roundup.
