Whistling along with the hymn, I strolled nonchalantly off toward the far end of the building.
I remembered that the housemaster’s study was located just inside the west door. Taking care to avoid the porter’s lodge, I made my way along the back of the building.
Sundays, I decided, are perfect for detective work. Everyone expects that Justice is set aside—at least until church or chapel lets out—and their guard is let down.
I met not a soul, and slipped as easily into Staircase No. 1 as if I were invisible.
The study was precisely where I had remembered it, with the name W. O. G. Denning lettered neatly on a card.
I suffered a brief pang as I realized I should have brought the keys from Mr. Denning’s pocket. Perhaps, though, a man of such authority would have no need to secure his doors: Respect would serve as its own lock and key. Even if he had shot the bolt, I could always count on my powers of lock-picking, for which I am eternally grateful to Dogger. A bent fork from the dining hall or a bit of stout wire from a stovepipe was as good as a Yale key in the right hands. As it turned out, though, I needn’t have worried: The door opened at a touch, and I had locked myself into the housemaster’s study before you could say “Spit!”
My stealth was wasted. The room was as empty of personal belongings as a tomb. Save for a foxed Christmas card from four years ago, propped open on a windowsill, addressed “Dear Mr. Denning,” and signed “Norah Willett (for the Battersea Dogs’ Home),” there was nothing but a bed, a desk, and a shelf of dusty schoolbooks. The desk drawers were empty except for a red pencil, a ruler, scissors, an India-rubber eraser, a box of drawing pins, and a spoon.
It was as if the man had no more needs than a phantom: as if he scarcely existed.
Although I checked under the mattress and pillows and inspected the undersides of drawers and the insides of rolled-up socks, my heart was not in it. I expected to find nothing, and nothing’s what I found.
I let myself out.
In order to reach the stairs, I had first to run the gauntlet of staring, black-framed faces that lined both sides of the hall: those Old Boys of Greyminster, students and masters, who had graduated into death “That Others Might Live,” as it said on each of the frames. I kept eyes front as I passed in review before these now-dead eyes, trying with all my strength not to break into a run before I reached the staircase.
At the back of the next floor up was the chemistry lab: a shameful jungle of unwashed flasks, stained beakers, and soiled petri dishes which showed clearly that Mr. Winter, the chemistry master, was more obsessed with Jaguars and speed than with cleanliness. I could have swatted him!
The blackboard was covered with equations, as well as a list of test results, upon which the names of Somerville and Plaxton led all the rest.
The chemicals were stored on shelves in a long, dim, narrow anteroom, and were arranged more or less alphabetically, although not always, since zinc sulfate came before sulfur. I could see, even before I came to it, what I was looking for. An empty space between calcium carbonate and hydrochloric acid showed that a large jar of copper sulfate was missing. I had no doubt that it would turn up sooner or later in one of the rubbish bins at Anson House. The question was this: Who had moved the jar from here to there? Fingerprints might or might not come to light, but all of that was still in the future.
For now, there was only one thing left to do before I took my leave. I erased a few of the chemical equations on the blackboard and, taking a stub of chalk in my left hand so as to obscure my handwriting, I wrote on the board in large letters: CLEANLINESS > GODLINESS, which could be read in several ways. Actually, I was quite proud of myself.
As I emerged into the quad, a stream of boys and masters came spilling out of the chapel’s open mouth. The sun had made its appearance, promising a fine day after all. I drifted slowly over to an old oak, where, after shedding and spreading my mackintosh, I sank demurely and sat with my hands folded in my lap, my placid face upturned to the sunshine in a slight smile. Somebody’s sister, up for Sunday tea and biscuits: no more, no less.
How easy it is, on the whole, to pull the wool over the eyes of men and boys.
As I waited for the worshippers to disperse, I began to review the facts and possibilities in the case.
First and foremost was the evidence of the tub itself, and the copper-plated body that remained seated in it, looking like nothing so much as an oversized motor-racing trophy. Not that it wasn’t tragic, and so forth, but still, in its own way, it was a spectacle second to none, and I was grateful to Plaxton for having called upon my services.
There was no doubt that the body had been copper-plated by one lead of the automobile battery having been dropped into the tub—filled at the time with a solution of copper sulfate—and the other clipped to the nose of the deceased like a clothes-peg.
The ring of sediment left behind was remarkable for its regularity: another clue that needed to be considered.
Identifying the culprit was going to be no easy task, I thought as I reviewed the suspects.
First of all, and top of my list because of his attitude, was Wilfrid Somerville. His father was an avid photographer, according to Plaxton, so it seemed reasonable to theorize that a certain awareness of chemicals would be inevitable in the son. Even the most careless observer would likely know that copper sulfate was sometimes used as a reversal bleach in the photo lab.
And then there was Lawson, whose father was a chemist in Leeds.
“Taffy”—Wagstaffe’s father—after his glorious career in the RAF, had taken up a hereditary post at the head of Wagstaffe Chemicals, a position into which the boy would likely someday follow him.
Henley, if my deductions were correct, came from a family made wealthy by plumbing supplies: a profession in which the use of copper sulfate to kill tree roots in sewer lines is known to every scullery maid. A medallion head of Henley senior—the family resemblance was remarkable—was stamped on every tin of their patent product, including the one that Dogger kept in the greenhouse at Buckshaw for emergencies, and I had recognized the son at once.
The chubby Smith-Pritchard, by contrast, seemed to have no obvious connection with the metal salts. The son of a member of Parliament, he appeared to be far more interested in stuffing food into his face than in fungicides.
That, except for Baker, was the first and second landings accounted for on Staircase No. 3, leaving only Cosgrave, Parker, and Plaxton himself, who had called me into the case.
Cosgrave was, of course, the son of Harrison Cosgrave, the noted—not to say famous, in certain circles—author of one of the standard works on chemistry.
Parker was the dark horse: the quiet one, the one who kept to himself and played American jazz on his gramophone in the small hours of the morning. Plaxton had said nothing about Parker’s family connections and it was quite clear that I needed to question Plaxton again.
One of these boys, I was certain, had had a hand in what I was already coming to think of as The Curious Case of the Copper Corpse. (It is no longer enough simply to solve crimes: We modern private detectives must also be able to come up with catchy names for our cases.)
My train of thought was interrupted by a footstep beside me. I looked up to see Plaxton steadying himself with a hand on the tree. He was breathing heavily, and even from a yard away I could almost hear his heartbeat.
“The jig is up,” he wheezed. “The head has sent out a search party for Mr. Denning. He was supposed to be at a housemaster’s breakfast at half-seven. He’s never missed in all his years.”
“Sit down beside me,” I said. “Don’t attract attention.”
Plaxton sat.
“Now, then,” I told him, “time is short. There are several points that need clarifying. What can you tell me about Baker?”
Baker was the only one of the nine students on Staircase No. 3 whom I had learned nothing about.
“Sandy Baker? He’s the little chap with glasses. Quite frail and a little hunched. You must have noticed him in my study.”
In fact I hadn’t, and I wasn’t proud of my slipup.
“He’s studying art and sculpture.”
“And his parents?” I asked.
