(3) Miss Mountjoy smelled of fish, too—cod-liver oil, judging by the vast quantities of the stuff that she keeps about Willow Villa.
(4) Brookie was killed (I believe) by a lobster pick shoved up his nostril and into his brain. A lobster pick from Buckshaw. (Note: Lobster is not a fish, but a crustacean—but still …) His body was left hanging on a statue of Poseidon: the god of the sea.
(5) When we found him hanging, Brookie’s face was fish-belly white—not that that means anything other than that he had been dangling from the fountain for quite a long time. Perhaps all night. Surely whoever had done this thing had done it during the hours of darkness, when there was little chance of being seen.
There are probably people abroad on the earth at this very moment who would be tempted to joke “There’s something fishy here.”
But I am not one of them.
As any chemist worth her calcium chloride knows, it’s not just fish that smell fishy. Offhand, I could think of several substances that gave off the smell of deceased mackerel, among them propylamine.
Propylamine (which had been discovered by the great French chemist Jean-Baptiste Dumas) is the third of the series of alcohol radicals—which might sound like boring stuff indeed, until you consider this: When you take one of the alcohols and heat it with ammonia, a remarkable transformation takes place. It’s like a game of atomic musical chairs in which the hydrogen that helps form the ammonia has one or more of its chairs (atoms, actually) taken by the radicals of the alcohol. Depending upon when and where the music stops, a number of new products, called amines, may be formed.
With a bit of patience and a Bunsen burner, some truly foul odors can be generated in the laboratory. In 1889, for instance, the entire city of Freiburg, in Germany, had to be evacuated when chemists let a bit of thioacetone escape. It was said that people even miles away were sickened by the odor, and that horses fainted in the streets.
How I wish I had been there to see it!
While other substances, such as the lower aliphatic acids, can be easily manipulated to produce every smell from rancid butter to a sweaty horse, or from a rotten drain to a goat’s rugger boots, it is the lower amines—those ragged children of ammonia—that have a most unique and interesting characteristic: As I have said, they smell like rotten fish.
In fact, propylamine and trimethylamine could, without exaggeration, be given the title “The Princes of Pong,” and I knew this for a fact.
Because she has given us so many ways of producing these smelly marvels, I know that Mother Nature loves a good stink as much as I do. I thought fondly of the time I had extracted trimethylamine (for another harmless Girl Guide prank) by distilling it with soda from a full picnic basket of Stinking Goosefoot (Chenopodium olidum), an evil-smelling weed that grew in profusion on the Trafalgar Lawn.
Which brought me back to Brookie Harewood.
One thing I was quite certain of was this: that the riddle of Brookie’s death would be solved not by cameras, notebooks, and measuring tapes at the Poseidon fountain, but rather in the chemical laboratory.
And I was just the one to do it.
I was still thinking about riddles as I slid down the banister and landed in the foyer. Nursery rhyme riddles had been as much a part of my younger years as they had anyone else’s.
Thirty white horses upon a red hill
Now they tramp, now they champ
Now they stand still.
“Teeth!” I would shout, because Daffy had cheated and whispered the answer in my ear.
That, of course, was in the days before my sisters began to dislike me.
Later came the darker verses:
One’s joy, two’s grief,
Three’s marriage; four’s a death.
The answer was “magpies.” We had seen four of these birds land on the roof while having a picnic on the lawn, and my sisters had made me memorize the lines before they would allow me to dig into my dish of strawberries.
I didn’t yet know what death was, but I knew that their verses gave me nightmares. I suppose it was these little rhymes, learned at an early age, that taught me to be good at puzzles. I’ve recently come to the conclusion that the nursery rhyme riddle is the most basic form of the detective story. It’s a mystery stripped of all but the essential facts. Take this one, for instance:
As I was going to St. Ives
I met a man with seven wives.
Each wife had seven sacks
Each sack had seven cats
Each cat had seven kits.
Kits, cats, sacks, wives
How many were going to St. Ives?
The usual answer, of course, is “one.” But when you stop to think about it, there’s much more to it than that. If, for instance, the teller of the rhyme happened to be overtaking the man with the traveling menagerie, the actual number—including sacks—would be almost three thousand!
It all depends upon how you look at things.
Mrs. Mullet was having her tea at the window. I helped myself to a digestive biscuit.
“The Hobblers,” I said, diving in with both feet. “You said they’d have my blood for sausages. Why?”
“You keep clear o’ them lot, miss, like I told you.”
“I thought they were extinct?”
“They smells just the same as everybody else. That’s why you don’t reck’nize ’em till somebody points ’em out.”
“But how can I keep clear of them if I don’t know who they are?”
Mrs. M lowered her voice and looked over both shoulders. “That Mountjoy woman, for one. God knows what goes on in ’er kitchen.”
“Tilda Mountjoy? At Willow Villa?”
I could hardly believe my good fortune!
“The very one. Why, it was no more than this morning I saw her in the Gully—headed for the Palings, she was, just as bold as brass. They still go there to do things with the water—poison it, for all I know.”
“But wait,” I said. “Miss Mountjoy can’t be a Hobbler—she goes to St. Tancred’s.”
“To spy, most likely!” Mrs. Mullet snorted. “She told my friend Mrs. Waller it was on account of the organ. The ’Obblesr got no organs, you know—don’t ’old by ’em. ‘I do love the sound of a good organ well played,’ she told Mrs. Waller, who told it to me. Tilda Mountjoy’s an ’Obbler born and bred, as was ’er parents before ’er. It’s in the blood. Don’t matter whose collection plate she puts ’er sixpences in, she’s an ’Obbler from snoot to shoes, believe you me.”
“You saw her in the Gully?” I asked, making mental notes like mad.
“With my own eyes. Since that Mrs. Ingleby come into her troubles I’ve been havin’ to stretch my legs for eggs. All the way out to Rawlings, now, though I must say they’re better yolks than Ingleby’s. It’s all in the grit, you know—or is it the shells? ’Course once I’m all the way out there, it makes no sense to go traipsin’ all the way back round, does it? So it’s into the Gully I go, eggs and all, and take a shortcut through the Palings. That’s when I seen her, just by Bull’s bonfires, she was—no more’n a stone’s throw ahead of me.”
“Did she speak to you?”
“Ho! Fat chance of that, my girl. As soon as I seen who it was I fell back and sat on a bank and took my shoe off. Pretended I’d got a stone in it.”
Obviously, Mrs. M had been walking in the same direction as Miss Mountjoy, and was about to overtake her—just like the person who was walking to St. Ives.
“Good for you!” I said, clapping my hands together with excitement and shaking my head in wonder. “What a super idea.”
“Don’t say ‘super,’ dear. You know the Colonel doesn’t like it.”
