The Sign at Six

by Stewart Edward White

For his share in the foregoing Percy Darrow was extensively blamed. It was universally conceded that his action in permitting Monsieur X to continue his activities up to the danger point was inexcusable. The public mind should have been reassured long before. Much terror and physical suffering might thus have been avoided—not to speak of financial loss. Scientific men, furthermore, went frantic over his unwarranted destruction of the formulas. Percy Darrow was variously described as a heartless monster and a scientific vandal. To these aspersions he paid no attention whatever.

Helen Warford, however, became vastly indignant and partisan, and in consequence Percy Darrow's course in the matter received from her its full credit for a genuine altruism. Hallowell, also, held persistently to this point, as far as his editors would permit him, until at last, the public mind somewhat calmed, attention was more focused on the means by which the man had reached his conclusions rather than on the use of them he had made.

The story was told three times by its chief actor: once to the newspapers, once to the capitalists from whom he demanded the promised reward, and once to the Warfords. This last account was the more detailed and interesting.

It was of a late afternoon again. The lamps were lighted, and tea was forward. Helen was manipulating the cups, Jack was standing ready to pass them, Mr. and Mrs. Warford sat in the background listening, and Darrow lounged gracefully in front of the fire.

"From the beginning!" Helen was commanding him, "and expect interruptions."

"Well," began Darrow, "it's a little difficult to get started. But let's begin with the phenomena themselves. I've told you before, how, when I was in jail, I worked out their nature and the fact that they must draw their power from some source that could be exhausted or emptied. You have read Eldridge's reasoning as to why he thought Monsieur X was at a distance and on a height. He took as the basis of his reasoning one fact in connection with the wireless messages we were receiving—that they were faint, and therefore presumably far distant or sent by a weak battery. He neglected, or passed over as an important item of tuning, the further fact that the instrument in the Atlas Building was the only instrument to receive Monsieur X's messages.

"Now, that fact might be explained either on the very probable supposition that our receiving instrument happened in what we may call its undertones to be the only one tuned to the sending instrument of Monsieur X; or it might be because our instrument was nearer Monsieur X's instrument than any other. This was unlikely because of the quality of the sound—it sounded to the expert operator as though it came from a distance. Nevertheless, it was a possibility. Taken by itself, it was not nearly so good a possibility as the other. Therefore, Eldridge chose the other.

"There were a number of other strictly scientific considerations of equal importance. I do not hesitate to say that if I had been influenced only by the scientific considerations, I should have followed Eldridge's lead without the slightest hesitation. But as I told him at the time, a man must have imagination and human sympathy to get next to this sort of thing.

"Leaving all science aside, for the moment, what do we find in the messages to McCarthy? First, a command to leave within a specified and brief period; second, a threat in case of disobedience. That threat was always carried out."

Darrow turned to Mrs. Warford.
