Lord Peter reached home about midnight, feeling extraordinarily wakeful and alert. Something was jigging and worrying in his brain; it felt like a hive of bees, stirred up by a stick. He felt as though he were looking at a complicated riddle, of which he had once been told the answer but had forgotten it and was always on the point of remembering.
“Somewhere,” said Lord Peter to himself, “somewhere I’ve got the key to these two things. I know I’ve got it, only I can’t remember what it is. Somebody said it. Perhaps I said it. I can’t remember where, but I know I’ve got it. Go to bed, Bunter, I shall sit up a little. I’ll just slip on a dressing-gown.”
Before the fire he sat down with his pipe in his mouth and his jazz-coloured peacocks gathered about him. He traced out this line and that line of investigation—rivers running into the sand. They ran out from the thought of Levy, last seen at ten o’clock in Prince of Wales Road. They ran back from the picture of the grotesque dead man in Mr. Thipps’s bathroom—they ran over the roof, and were lost—lost in the sand. Rivers running into the sand—rivers running underground, very far down—
Where Alph, the sacred river, ran
Through caverns measureless to man
Down to a sunless sea.

By leaning his head down, it seemed to Lord Peter that he could hear them, very faintly, lipping and gurgling somewhere in the darkness. But where? He felt quite sure that somebody had told him once, only he had forgotten.
He roused himself, threw a log on the fire, and picked up a book which the indefatigable Bunter, carrying on his daily fatigues amid the excitements of special duty, had brought from the Times Book Club. It happened to be Sir Julian Freke’s “Physiological Bases of the Conscience,” which he had seen reviewed two days before.
“This ought to send one to sleep,” said Lord Peter; “if I can’t leave these problems to my subconscious I’ll be as limp as a rag tomorrow.”
He opened the book slowly, and glanced carelessly through the preface.
“I wonder if that’s true about Levy being ill,” he thought, putting the book down; “it doesn’t seem likely. And yet—Dash it all, I’ll take my mind off it.”
He read on resolutely for a little.
“I don’t suppose Mother’s kept up with the Levys much,” was the next importunate train of thought. “Dad always hated self-made people and wouldn’t have ’em at Denver. And old Gerald keeps up the tradition. I wonder if she knew Freke well in those days. She seems to get on with Milligan. I trust Mother’s judgment a good deal. She was a brick about that bazaar business. I ought to have warned her. She said something once—” 166
He pursued an elusive memory for some minutes, till it vanished altogether with a mocking flicker of the tail. He returned to his reading.
Presently another thought crossed his mind aroused by a photograph of some experiment in surgery.
“If the evidence of Freke and that man Watts hadn’t been so positive,” he said to himself, “I should be inclined to look into the matter of those shreds of lint on the chimney.”
He considered this, shook his head and read with determination.
Mind and matter were one thing, that was the theme of the physiologist. Matter could erupt, as it were, into ideas. You could carve passions in the brain with a knife. You could get rid of imagination with drugs and cure an outworn convention like a disease. “The knowledge of good and evil is an observed phenomenon, attendant upon a certain condition of the brain-cells, which is removable.” That was one phrase; and again:
“Conscience in man may, in fact, be compared to the sting of a hive-bee, which, so far from conducing to the welfare of its possessor, cannot function, even in a single instance, without occasioning its death. The survival-value in each case is thus purely social; and if humanity ever passes from its present phase of social development into that of a higher individualism, as some of our philosophers have ventured to speculate, we may suppose that this interesting mental phenomenon may gradually cease to appear; just as the nerves and muscles which once controlled the 167 movements of our ears and scalps have, in all save a few backward individuals, become atrophied and of interest only to the physiologist.”
“By Jove!” thought Lord Peter, idly, “that’s an ideal doctrine for the criminal. A man who believed that would never—”
And then it happened—the thing he had been half-unconsciously expecting. It happened suddenly, surely, as unmistakably, as sunrise. He remembered—not one thing, nor another thing, nor a logical succession of things, but everything—the whole thing, perfect, complete, in all its dimensions as it were and instantaneously; as if he stood outside the world and saw it suspended in infinitely dimensional space. He no longer needed to reason about it, or even to think about it. He knew it.
There is a game in which one is presented with a jumble of letters and is required to make a word out of them, as thus:
C O S S S S R I
The slow way of solving the problem is to try out all the permutations and combinations in turn, throwing away impossible conjunctions of letters, as:
S S S I R C
or
S C S R S O
Another way is to stare at the inco-ordinate elements until, by no logical process that the conscious mind 168 can detect, or under some adventitious external stimulus, the combination:
S C I S S O R S
presents itself with calm certainty. After that, one does not even need to arrange the letters in order. The thing is done.
Even so, the scattered elements of two grotesque conundrums, flung higgledy-piggledy into Lord Peter’s mind, resolved themselves, unquestioned henceforward. A bump on the roof of the end house—Levy in a welter of cold rain talking to a prostitute in the Battersea Park Road—a single ruddy hair—lint bandages—Inspector Sugg calling the great surgeon from the dissecting-room of the hospital—Lady Levy with a nervous attack—the smell of carbolic soap—the Duchess’s voice—“not really an engagement, only a sort of understanding with her father&r............
