Earlier this month, I
reviewed Todd Downing's The
Last Trumpet (1937), a minor gem of the North American
regional mystery novel, which Coachwhip
reprinted as a paperback in 2012 and discovered at the time a handful
of Downing's Hugh Rennert novels were reissued in March as ebooks –
courtesy of MysteriousPress/Open
Road. Since we're about a month into the summer, I decided to
delve into the sultry-sounding Murder on the Tropic (1935). I
was not disappointed!

Edward Solier is a Texas
businessman with an interest in a remote, isolated hacienda down in
Mexico, named Flores, which had been bought based on certain
information that the new Pan-American Highway, to Mexico City, would
cut through the track of land and wanted to erect a luxurious hotel
on the spot – a plan that was spoiled when the route of the highway
was changed. So now he was left with an isolated and practically
useless property on his hands.
A company had been formed
to buy the property and build the hotel, which sold shares, but now
they want to get rid of it. Only problem is that one person refuses
to sell back her block of shares.
Miss Bertha Fahn is a
botanist who invested a small sum of money and has been staying at
the hacienda to do "some kind of a study of plants and flowers,"
but they have no idea why she flatly refuses to sell. Or why she
requested 126 postcards. Solier wants Rennert to persuade Miss Fahn
to sell back her shares and find out who has been emptying bottles of
water during the night, which is becoming a problem now that springs
are drying up and the place is becoming dependent on bottled water.
Rennert accepts an easy paycheck, but discovers that the quiet,
isolated hacienda has a palpable "undercurrent of repressed
emotions" and compared his task with "sitting on top of a
volcano."
When he arrived at the
hacienda, there are eight people: Solier's two business partners in
the failed project, Tilghman Falter
and George Stahl, but Stahl unexpectedly died of sunstroke and his
interest went to his stepson, Mark Arnhardt – who's also present at
the hacienda. Stephen Holman is the architect who designed to the
hotel, but came down with tuberculosis and stayed there with his
wife, Ann, in the hope that the climate would help him. Esteban
Flores is a young Mexican whose airplane crashed there and is trying
to get new parts to repair the plane, but the place used to belong to
his family. And he spends his time searching for the long-lost body
of his grandfather. Miguel and Maria Montemayor have been caretakers
of the hacienda since the days of Flores' grandfather. Lastly,
there's the stubborn Miss Fahn and the Chinese cook, Lee, who returns
from a family trip after Rennert's arrival.
All
of these characters come with a little side-mystery that has to be
solved or else carry a piece of the puzzle, which means Rennert has
to clear a lot of debris before he can reveal who has been behind a
series of very subtly executed murders. A series poisonings with all
the unnerving and fantastic eeriness of John
Dickson Carr!

Hacienda
Flores is situated in "a
hidden pocket of the mountains,"
on the Tropic of Cancer, where "a
precipitous valley debouched onto the desert."
Downing doesn't relay on cheap or crude plot-devices to completely
seal the characters away from the outside world. There's a short-wave
radio set that allows constant communication with the outside world,
but it gets through the story undamaged and the tropical hurricane
lurking in the background only temporarily hinders their movement
towards the end. Regardless of these exists, or air holes, Murder
on the Tropic is one of
the best and most convincing isolation-mysteries on the book. You
really get the idea that the characters are tucked away in a lonely,
nearly unreachable pocket of the world. Even though that's not
entirely the case (they get bottled water trucked to them everyday),
but the illusion of isolation is very convincingly and effectively
done.
There
are, however, two weak spots in an otherwise solid and cleverly
constructed plot: the clueing is a little iffy in certain places
(such as the nature of poison) and even with the clues that were
given, the twist ending is easily anticipated – because the
murderer (sort of) stands out. A kind of cliche that will make any
seasoned mystery reader suspicious. But these minor drawbacks were
hardly enough to ruin an engagingly written and leisurely plotted
detective novel. A detective novel full of dreamlike, but often
unsettling, mysteries and wonder of the desert.
Honestly,
if Murder on the Tropic
had been published 5-10 years later, I would have assumed Downing had
been trying to emulate some of Agatha
Christie most well-known mysteries, but she had not yet written
Murder
in Mesopotamia
(1936), Death
on the Nile (1937),
And
Then There Were None
(1939) and Evil
Under the Sun (1941)
at the time. So, if you liked any of those titles, you'll likely find
a lot to enjoy in Murder
on the Tropic.
I'll
end this review with a warning to everyone who's new to Todd Downing:
don't begin with The Cat
Screams (1934), because
its an inferior work compared to Murder
on the Tropic and The
Last Trumpet that has
kept me away from Downing for nearly a decade. But now that I have
rediscovered him, I'll try to read and review The
Case of the Unconquered Sisters
(1936) and Death Under
the Moonflower (1939)
before the summer draws to a close.
