Once more and not for the last time, in setting down such phrases as these, I realize how ridiculous they must sound to any one who does not know to begin with what they signify and what is the exact truth that lies hidden in them. Nevertheless, I declare that this idea of something absurd and impossible did not occur to the mind when it was confronted with the phenomenon. Even when no theory had as yet suggested the smallest element of a logical explanation, people accepted as irrefutable the evidence of their own eyes. All those who saw the thing and whom I questioned gave me the same answer. _Afterwards_, they would correct themselves and protest. _Afterwards_, they would plead the excuse of hallucinations or visions received by suggestion. But, at the time, even though their reason was up in arms and though they, so to speak, "kicked" against facts which had no visible cause, they were compelled to bow before them and to follow their development as they would the representation of a succession of real events. A theatrical representation, if you like, or rather a cinematographic representation, for, on the whole, this was the impression that emerged most clearly from all the impressions received. The moment Miss Cavell's image had assumed the animation of life, I turned round to look for the apparatus, standing in some corner of the Yard, which was projecting that animated picture; and, though I saw nothing, though I at once understood that in any case no projection could be effected in broad daylight and without omitting shafts of light, yet I received and retained that justifiable impression. There was no projector, no, but there was a screen: an astonishing screen which received nothing from without, since nothing was transmitted, but which received everything from within. And that was really the sensation experienced. The images did not come from the outside. They sprang to the surface from within. The horizon opened out on the farther side of a solid material. The darkness gave forth light.
