Color Scheme

“Oh, for God’s sake,” Gaunt said wearily.

“Four apparently inexplicable points have interested me enormously. The railway signal. Eru Saul’s shirt. The pohutukawa trees. The misplaced flag. It seems to me that if an explanation is found that will apply equally to these four parts, then we shall have gone a long way towards solving the whole. These are factual things.”

“How about yourself?” Simon demanded abruptly. “If it comes to facts you look pretty fishy, don’t you?”

“I am coming to myself,” said Mr. Falls modestly. “I look extremely fishy. I have left myself to the last because what I have to say, or part of it, is in the nature of a confession.”

Webley looked up quickly. He moved his chair back a little and shifted the position of his great feet.

“When I left the hall,” said Mr. Falls, “I went immediately into the thermal reserve. I have stated that I saw Questing ahead of me and recognized him by his overcoat. I have also stated that I paused and lit my pipe, that I then heard Questing scream, and that a few moments later Bell came along from the direction of the village. I had no alibi. Later, having insisted that none of us should return to the scene of the crime, I myself returned there. You saw me from the hill, did you not, Bell? I was obliged, by the nature of my errand, to use my torch. I heard you plunging down the hillside and realized that you must have seen me. On my return I informed Colonel Claire and Dr. Ackrington of my visit to the forbidden territory. Later, I believe, they told you I had given, as an excuse, a story that I had heard someone moving about on the other side of the mound. This was untrue. There was nobody there. And now,” Falls continued, “I come to the last episode in my story.” With a swift movement he thrust his hand inside his jacket.

Simon scrambled to his feet with an inarticulate cry.

“Grab him!” he shouted. “Grab him! Quick! Before he takes it! Poison!”

But it was not a phial or deadly capsule that Mr. Falls drew from the i

“You alarm me terribly,” said Mr. Falls. “What on earth are you up to?”

“Sit down, boy,” said Dr. Ackrington, “you’re making a fool of yourself.”

“What the blazes are you gettin‘ at, Sim?” asked his father. “Plungin’ about like that?”

Gaunt laughed hysterically and Simon turned on him.

“All right, laugh! The man stands there and tells you he lied, and you think it’s fu

“Ah!” said Mr. Falls. “You noticed my experiment on the verandah, did you? I thought as much. You have what used to be called a speaking countenance, Claire.”

“You admit it was the code signal? You admit it?”

“Certainly. An experiment to test Questing. It had an unfortunate result. He picked up the pipe. Quite i

“That’s right,” said Simon. “You.”

“But I see,” Mr. Falls continued urbanely, “that you are looking at this piece of yellow celluloid which I hold in my hand. I cut it off Questing’s sun-screen on his car. Its colour is important. Colour, indeed, plays a significant part in our story. If you look at a red object through this celluloid it becomes a different shade of red, but it is still red. If you look at a green object through it, a similar phenomenon occurs. A blue-green, such as one may see on a railway signal, merely becomes a slightly warmer yellowish green. If Questing said that he mistook the red signal because he saw it through this celluloid, he lied.”

“Yes, but damn it all…” Simon began, and got no further.

“Questing stated that on the occasion of his almost fatal signal to Mr. Smith at the railway bridge, Eru Saul wore a blue shirt, but we know that he wore a pink one. Did he lie again? That same evening he fell into Dr. Ackrington’s trap, and agreed that there was no bloom on the trees at Pohutukawa Bay, when, as a matter of fact, the Bay was, and still is, scarlet with blossom. Again, did he lie? Dr. Ackrington, most naturally, concluded that he had not been to the Bay, but we know now that he had. Here I should tell you, in parenthesis, that Mr. Questing’s pyjamas and ties exhibit a recurrent theme of the peculiar shade of puce which it seems he did not recognize in Eru Saul’s shirt. Now we come to the final scene.”

Webley got quickly to his feet. One of the men on the verandah opened the door and came in. He, too, moved quietly. Dikon thought that only he and Gaunt had seen him and his manoeuvre. Gaunt looked quickly from this man to Webley.

“Questing,” said Mr. Falls, “carried a torch when he crossed the thermal reserve. The moon was not yet up and he flashed his torch-light on the white flags that marked the path he must follow. When he reached the mound above Taupo-tapu, over which the track passes, he would see no white flags ahead of him for the one on the top had been displaced. He would, however, see the faded red flags marking the old path on which Taupo-tapu has now encroached. There are several mounds on both sides of Taupo-tapu and they look much alike by torch-light.

“My contention is that Questing followed the red flags and so came by his death. My contention is that Questing’s murderer is the man who knew that he was colour-blind.”

A sharp flick to that fascinating toy, the kaleidoscope, will transfer a jumble of fragments into a symmetrical design. To Dikon, it seemed that Mr. Falls had administered just such a flick to the confused scraps of evidence that had collected about the death of Maurice Questing. If the completed pattern was not yet fully visible it was because there was some defect, not in the design but in Dikon’s faculty of observation. The central motif, the pivot of the system, was still hidden from him but it began to emerge as Falls, disregarding the sharp exclamations that broke from his listeners, and the emphatic slap with which Dr. Ackrington brought his palm down on the table, went on steadily with his exposition. The affectations, and the excessive urbanity of ma

“Now, it is a characteristic of persons afflicted with colour-blindness that they are most reluctant to admit to this defect. The great Hans Gross has noted this curious attitude and says that a colour-blind person, if he is forced to confess to his affliction, will behave as if he was guilty of some crime. Questing, when challenged by Dr. Ackrington with an attempt to cause the death of Mr. Smith, instead of admitting that he could not distinguish the red signal from the green, said that the signal was not working. Mr. Smith fold you that, later on, Questing gave him the story of the celluloid sun-screen.”

“Yes, but look here…” Simon began and stopped short. “On your way,” he said.

“Thank you. It is also characteristic of these people that they confuse green with red and they have a predilection for that peculiar shade of pink, kaffir pink or puce as it is sometimes called, which, apparently, seems to them to be blue. A patch of red if seen by green torch-light might appear to these people to be colourless. At any rate, with the white flag removed, Questing, if colour-blind, would have no standard of comparison and would most certainly expect the red flag to be white and accept it as such. Accepting for the moment my theory of Questing’s colour-blindness, let us see how it squares up with the evidence of the track. Sergeant Webley,” said Mr. Falls with a slight return to his old mellifluous style, “will correct me if I am wrong. My own investigation took place by torch-light, remember.”
