Without the dead man, the cucumber patch was oddly uninteresting, no more than a patch of greenery with here and there a broken stalk and something that looked suspiciously like the drag mark of a heel. In the grass, I could see the perforations where the sharp legs of Sergeant Woolmer's heavy tripod had pierced the turf.
I knew from listening to Philip Odell, the private eye on the wireless, that whenever there's a sudden and unexpected death, there's bound to be a postmortem, and I couldn't help wondering if Dr. Darby had yet had the body—as I had heard him remark to Inspector Hewitt—“up on the table.” But again, that was something I dared not ask, at least not just yet.
I looked up at my bedroom window. Reflected in it, so close I could almost touch them, images of plump white clouds floated by in a sea of blue sky.
So close! Of course! The cucumber patch was directly below my window!
Why, then, had I heard nothing? Everyone knows that the killing of a human being requires the exertion of a certain amount of mechanical energy. I forget the exact formula, although I know there is one. Force applied in a short span of time (for instance a bullet), makes a great deal of noise, whereas force applied more slowly may well make no noise at all.
What did this tell me? That if the stranger had been violently attacked, it had happened somewhere else, somewhere out of earshot. If he had been attacked where I found him, the killer had used a silent method: silent and slow since, when I found him, the man had been still, although barely, alive.

I needed to think—and to think without distractions. The coach house was out of the question since I was now aware that, in times of trouble, I might well encounter Father sitting there in Harriet's Phantom. That left the Folly.
On the south side of Buckshaw, on an artificial island in an artificial lake, was an artificial ruin, in the shadow of which was a little Greek temple of lichen-stained marble. Now sunk deep in neglect and overgrown with nettles, there had been a time when it was one of the glories of England: a little cupola on four exquisitely slender legs that might have been a bandstand on Parnassus. Countless eighteenth-century de Luces had poled their guests out to the Folly on festive flower-strewn barges, where they had picnicked upon cold game and pastry as they watched the swans glide across the glassy water, and looked through quizzing-glasses at the hired hermit as he gaped and yawned at the doorway of his ivy-clad cave.
The island, the lake, and the Folly had been designed by Capability Brown (although this attribution had been brought into question more than once in the pages of
There was a family tradition that it had been on a picnic at Buckshaw Folly that John Montague, the fourth Earl of Sandwich, invented the snack which was given his name when he first slapped cold grouse between two slices of bread while playing at cribbage with Cornelius de Luce.
'History be damned,' Father had said.
Now, having waded out to the island through water no more than a foot deep, I sat on the steps of the little temple with my legs drawn up and my chin on my knees.
First of all, there was Mrs. Mullet's custard pie. Where had it gone?
I let my mind drift back to the early hours of Saturday morning: envisioned myself coming down the stairs, going through the hallway to the kitchen, and—yes, the pie had certainly been on the windowsill. And there had been a single piece cut out of it.
Later, Mrs. Mullet had asked if I enjoyed the pie. Why me? I wondered. Why didn't she ask Feely or Daffy?
And then it struck me like a thunderclap! The dead man had eaten it. Yes. Everything was making sense!
Here was a diabetic who had come on a long journey from Norway, bringing with him a jack snipe concealed in a pie. I had found the remains of that pie—complete with telltale feather—at the Thirteen Drakes, and the dead bird had been dumped on our doorstep. Not having eaten—even though, according to Tully Stoker, he had been served a drink in the saloon bar—the stranger had made his way to Buckshaw on Friday night, quarreled with Father, and on his way out passed through the kitchen and helped himself to a slice of Mrs. Mullet's custard pie. And he hadn't made it through the cucumbers before it brought him down!
What kind of poison could work that quickly? I ran through the most likely possibilities. Cyanide worked in minutes: after turning blue in the face, the victim was asphyxiated almost immediately. It left behind a smell of bitter almonds. But no, the case against cyanide was that, had it been used, the victim would have been dead before I found him. (Although I have to admit that I have a soft spot for cyanide—when it comes to speed, it is right up there with the best of them. If poisons were ponies, I'd put my money on cyanide.)
But was it bitter almonds I had smelt on his last breath? I couldn't think.
Then there was curare. It, too, had an almost instant effect and again, the victim died within minutes by asphyxiation. But curare could not kill by ingestion; to be fatal, it had to be injected. Besides that, who in the English countryside—besides me, of course—would be likely to carry curare in his kit?
What about tobacco? I recalled that a handful of tobacco leaves left to soak in a jar of water in the sun for several days could easily be evaporated to a thick black molasses-like resin which brought death in seconds. But
Since nobody smoked at Buckshaw, I would have to gather my own samples.
THE REAL QUESTION WAS THIS: Who put the poison in the pie? And, even more to the point, if the dead man had eaten the thing by accident, whom had it originally been intended for?
I shivered as a shadow passed across the island, and I looked up just as a darkening cloud blotted out the sun.
