Tragedy at the Unicorn (1928) is only the fifth novel, of more than seventy, in the Dr. Lancelot Priestley series by "John Rhode," a pseudonym of John Street, which used to be one of his many out-of-print, hard to get and expensive titles to get a hold-of – until Spitfire Publishers reprinted it last year. Rhode's Tragedy at the Unicorn also used to be one of those rare, out-of-print impossible crime novels from a well-known mystery writer and the reason why it had been on my locked room wishlist for ages. So this is another obscure title that can be crossed off the list.
Tragedy at the Unicorn takes place in-and around the Unicorn Hotel in the seaport town of Clayport, "one of the best-known yachting centres on the south coast," which is run by Mrs. Burgess and her two daughters, Joan and Phyllis. Clayport is the home port of the Levity, a ketch, belonging to Bob Weldon, the skipper. Levity's crew comprises of Richard Gateman, Percy Hunter and the story's narrator, Mr. Attercliffe, who are all frequent guests at the Unicorn Hotel. But they're not the only guests who checked in on that late summer afternoon. There's Edward Motimer, a yachtsman, who owns a motor cruised named Dreamland, the detestable Dr. Victor Grinling and his valet, Ferguson. And, of course, it's the caustic Dr. Grinling who's going to end up causing trouble for everyone.
Next morning, Ferguson is unable to wake his master ("let sleeping Grinlings lie") and it takes a while before they can unlock the bedroom, but, when they finally go inside, they find Dr. Grinling lying "stone dead" in his bed. An empty syringe is found on the bedside table alongside a phial with small tablets of heroin ("one-sixth of a grain"). So remember the previous review in which I pointed out Helen McCloy's Dance of Death (1938) was written during a period when heroin was an over-the-counter drug? I couldn't have randomly picked a better book to make that point as Dr. Gringling was in the habit of taking "heroin injections for sleeplessness," remarking "he would have no difficulty obtaining the stuff" and "would know it would do him no harm" – "unless he took an overdose." If I were a publisher, I probably would have inserted a bunch of vintage ads for heroin cough drops and cocaine-laced "patent medicines" ("COCAINE TOOTHACHE DROPS, NOW WITH EVEN MORE COCAINE!"). That's not all.
A postmortem reveals had injected heroin, but what killed him was a second injection with morphia. Not the heroin. There were morphine tablets mixed with his heroin tablets, "all similar in appearance," which could make an accidental overdose, suicide or murder ("MRS. WINSLOW'S SOOTHING SYRUP FOR TEETHING CHILDREN, NOW WITH EVEN MORE MORPHINE!!"). Superintendent Collins is the first to take a crack at the case, but Dr. Priestley arrives right before the halfway mark to take charge of the investigation. This is, of course, one of Dr. Priestley's earlier cases and has yet to become the sedentary armchair oracle of later books. So the chapter following his arrival sees him all over the hotel to inspect and oil locks and hinges. Unfortunately, this proves to be short-lived as Tragedy at the Unicorn regrettably ended up being a flawed, undefined work of its time and an author who still has to find his footing in the genre.
The 1920s was a decade when the Golden Age detective story of the 1930s and '40s was taking shape and solidifying, which naturally came with some growing pains. Tragedy at the Unicorn goes from a promising, early Golden Age whodunit during the first-half to an uninspired, routine thriller in the second-half – involving a smuggling operation (of course). That's not a spoiler. It's patently obvious from the start smuggling is going on the background and it became the focal point of the second-half. Funnily enough, the smuggling operation is partly run by a Dutch gang peddling drugs between Clayport and Rotterdam, because why not ("THE NETHERLANDS, NOW WITH EVEN MORE CANNABIS!!!"). Dr. Priestley even translates a telegram in Dutch, even though his "knowledge of Dutch is not very extensive." Other than that, it has nothing noteworthy or anything particular to recommend. Just a smugglers doing what smugglers do.
So what about the murder of Dr. Grinling? The locked room setup looked promising: a solid door locked from the inside with the key still in the lock that "turns very stiffly." Only window was shut and fastened. The connecting door was locked with the key hanging on a board Joan's bedroom and blocked on both sides of the door by heavy washing stands. More than enough room to work out a halfway decent locked room-trick, but Rhode kept the locked room-trickery very rudimentary and very, very disappointing. Rhode at least tried to do something with the murderer's identity and motive, but the result is not exactly the stuff of classics. Both obvious and disappointing. So, simply as a detective novel or locked room mystery, Rhode's Tragedy at the Unicorn has nothing to offer or recommend. Unless you're a John Street completist or one of those nuts trying to go through every title Robert Adey listed in Locked Room Murders (1991). Rhode was much more successful with the impossible crime story in novels like Invisible Weapons (1938), Death in Harley Street (1946) and the "Miles Burton" novel Death in the Tunnel (1936). So I'll recommend them instead.
Note for the curious: why not end with a halfway decent solution, for 1928, to the locked room that occurred to me after the murder was discovered. What if Dr. Grinling told his killer to come to his room after he retired, but instructed the killer to come through the connecting door. Yes, the killer has a way to unlock the door. So they move aside the washstands, the killer unlocks the connecting door and enters to conduct their shady business. The killer is, of course, well aware of Dr. Grinling's habit to take a shot of heroin before going to sleep and brought along a syringe loaded with morphia. When the doctor was distracted, the killer swapped the heroin syringe for the morphia one. The killer left the room, locked the connecting door, washing stands returned to their original place and Dr. Grinling took his deadly injection in a perfectly locked room. This brilliant piece of armchair reasoning fell apart when it was shown he had taken both the heroin and morphia injections. At least I enjoyed cranking out this review.
