What does Huxter notice about Mr. Marvel? What happens to Huxter? What does Huxter think has taken place?

From the text:

Forthwith Mr. Huxter, conceiving he was witness of some petty larceny, leapt round his counter and ran out into the road to intercept the thief. As he did so, Mr. Marvel reappeared, his hat askew, a big bundle in a blue table-cloth in one hand, and three books tied together—as it proved afterwards with the Vicar's braces—in the other. Directly he saw Huxter he gave a sort of gasp, and turning sharply to the left, began to run. "Stop, thief!" cried Huxter, and set off after him. Mr. Huxter's sensations were vivid but brief. He saw the man just before him and spurting briskly for the church corner and the hill road. He saw the village flags and festivities beyond, and a face or so turned towards him. He bawled, "Stop!" again. He had hardly gone ten strides before his shin was caught in some mysterious fashion, and he was no longer running, but flying with inconceivable rapidity through the air. He saw the ground suddenly close to his face. The world seemed to splash into a million whirling specks of light, and subsequent proceedings interested him no more.
