THE STORY: William Power, lawyer, confides with his married novelist friends, Vincie and Penny Mercer, on an unusual murder involving what appears to be a poisoning by inhalation. Evidence suggests that a boutonniere found on the victim's lapel was dusted with cocaine. The two writers are enlisted as unofficial detectives and together the three solve the murder with a very strange method of killing and even more odd motive.
THE CHARACTERS: William Power along with the Mercers appear in a brief series of detective novels by John Hazlette Vahey writing under the pseudonym Henrietta Clandon. Vahey is better known to readers of this blog as
Vernon Loder whose mystery novels incorporate bizarre plots, strange murder methods and his trademark sense of offbeat humor.
Power on the Scent (1937) is the fourth book in the series of five, but only the third in which the three series characters appear together. Powell appears alone in
Good by Stealth (1937) while the Mercers go it alone in the final Clandon novel
Fog over Weymouth (1938).
Penny and Vincie are novelists who specialize in crime fiction and detective stories. Penny's last work was released as
This Delicate Murder, the previous novel in the Clandon series, and we find out that Penny writes as "Henrietta Clandon" adding an element of metafiction to this series. The previous case is alluded to several times and even footnoted in the text.

Penny comes up with a handful of good ideas as to how the cocaine was administered when an elaborate re-creation of a flower delivery fails to show that the rose used as a boutonniere could have held onto the powdered drug over the rough road the bicyclist travelled. When she learns that the victim had a fondness for the candy Turkish Delight she offers up the traditional coating of confectioner's powered sugar could easily have been doctored and not been noticed. That the victim is also a "snuffer" (translation for US readers: drug snorter) suggests that he may not have sensed the difference to an added sprinkling of coke on his candy. The detective work here is filled with interesting ideas and action like the flower delivery by bicycle re-enactment that Vincie performs for Power and the police.
The title of novel comes into play at various places. We get discussions of the scent of flowers, perfumes, and the apparently fading habit of people smelling flowers. When Power passes by a garden at night and smells the pungent odor of tobacco plants which he tells us release their scent at night he once again gets to thinking of botanical scents. It turns out to be the detection climax of the book.
Overall, I would call
Power on the Scent a didactic detective novel. The bulk of the detection is done via conversations at afternoon tea, restaurant meals and dinner parties. It's detection as a social gathering. Almost all of it exclusively through dialogue as well. Late in the book is one excellent scene where Powell invites Dr. Terpis, forensic pathologist, to dinner at the Mercer home. Dr. Terpis is perhaps the liveliest character in the entire book. He was certainly my favorite.
Terpis is described as "no more than thirty, fat, red-faced, with a perpetual smile and a hoarse laugh which broke out on the least provocation." He is amateur puppeteer and entertains Penny's interest in the art form with tales of his puppet making and his work on writing plays for his gallery of puppets. He enjoys every course of the meal prepared for him ("It was as good as eating yourself to watch his gastronomic pleasure") and is a pleasant raconteur as well as an informative forensics expert. When Terpis comes to discuss the case he presents fascinating details about the skull of a Great Dane that went over a cliff with one of the suspects, both perished. His findings, both macabre and pertinent to the case, will help clear up some ambiguities, decide the actual method of murder, and lead to the surprising solution to the various mysteries uncovered in the death of Montague Morgan, stockbroker and developer of a unique variety of Rennavy Rose.
INNOVATIONS: As "Henrietta Clandon" Vahey indulges in a self-consciously witty style, overflowing with puns, epigrams and arch humor. It's a humor reminiscent of Restoration comedies of Wycherley and Etherege and seems utterly out of place in this detective story plot with its grave consequences involving murderous rage and drug abuse. Other writers use this arch humor to great effect like Christianna Brand and Colin Watson without characters willfully drawing attention to their own cleverness. I was bothered by how delighted Penny and Vince were with each other when they came up with yet another ridiculous pun. Even Powell joins in on the game. The dialogue is loaded with the kind of epigrammatic sentences you find too often in the plays of Oscar Wilde. People don't talk this anywhere except in books, on stage and in cocktail comedies of 1930s American cinema. In a detective novel that does not start out as a farce the self-conscious humor sticks out like a sore thumb. This is not to say I didn't find some of it clever or amusing; some of it is (see QUOTES section). However, when the characters comment on their cleverness and practically pat each other on the back when some witticism is delivered I was rolling my eyes.

THINGS I LEARNED: The victim's nephew Charles Sibbins has hired Powell to look into his uncle's suspicious death. He's a playboy and spendthrift who at the start of the book is hunting
bongos in Afirca. I always though a bongo was a type of drum. Guess again! Bongos are a type of striped antelope with distinctive curved horns indigenous to to Western Africa. (see photo) Currently there are only 150 still living in the wild. Luckily, their home is a preserve in the Kenyan mountains where hopefully they are safe from marauding poachers who seem to be solely responsible for the decimation of hundreds of animals species in that continent.
Penny refuses to use the hateful term
macrocarpa to describe a hedge behind which Morgan was found. She says why say that when its easier and smarter to use cypress. A macrocarpa is, after all, a form of cypress -- the Monterey cypress, in fact. The very type of cypress clinging for life on the
cliffs of Carmel, CA that has been photographed innumerable times and appears all over the internet.
On page 158 there is this sentence: "Noses, '
narks' as they used to be called, are very useful but rarely men with any moral sense." This is most likely the origin of the crime world slang term spelled as 'narc' in the US. I always thought
narc was derived from the word
narcotic. Nark and nose here are meant as slang for
police informer.
Nark first appeared in print in 1859 as the Merriam-Webster wizards of lexicography and etymology informed me. They suggest it derives from
nak, Romani (the Gypsy language) for nose.
Another odd word on page 175 "Morgan...might be tempted to risk his money on a
stumer..." sent me to the internet dictionaries once more. I learned that this is British slang for fraud or failure, especially a horse race that was rigged or fixed. It can also refer to the person who was victimized from such a rigged horse race.
And -- of course--
dog in the manger cropped up again! ("There was no suggestion of tender passages between them. He was either a dog-in-the-manger, or she was a superlative typist. They are, I hear, rare in the City.") For those who are counting that makes the third appearance of the phrase in two months for the books reviewed here. How have I never heard or read it until this year?
QUOTES: Summing up Charles Sibbins, an avid hunter, as a loudmouth coward Power says:
"
You take it from me that if bongos went about with sub-machine guns Sibbins wouldn't collect many."
"You're spoiling the whole thing! You people full of commonsense are the death of all imagination!"
Impartiality is a gift of the gods and they are more sparing of it than anything else.
"The fact is that Withers has got the wind up, and I always find it pays to let the wind do its work," [Penny said]
"Very right," Vincie agreed, "practical and alliterative."
Vagueness is a virtue in a practicing policeman. He can always say that he didn't mean what you mean.
"I warned him against that dog several times. In fact, I hated the beast. It may seem unkind to say so, but over-kind and friendly people, and over-affectionate dogs are definitely dislikeable."
"Does it not occur to you that a man or woman tells the truth more often when he is rude, then when he is civil and polite?"
"Politeness is as much an enemy of the truth as oil is of friction."
EASY TO FIND? But of course! How's that for a welcome surprise. Four of the books written by Vahey using the Clandon pen name have been reissued by the prolific vintage crime novel reprint publisher
Dean Street Press. In addition to
Power on the Scent you can purchase a copy of
Good By Stealth (already favorably reviewed
here and
here),
Inquest and
This Delicate Murder. All four were officially released on March 2 and are now available for sale in paperback and digital formats. The original UK editions of the Henrietta Clandon mystery novels are extremely scarce. None of them were published in the US during Vahey's lifetime. Some like
Fog over Weymouth have not been available in the used book market in decades. There are a handful out there, but I suggest that you purchase the new editions as they include informative introductory material by Curt Evans who offers up his usual biographical tidbits and insights into the writer's work.
