Brandon’s face had an ever-deepening interest, but he did not venture upon a remark.

“Of course,” said the vicar, “one’s answer should have been, ‘My friend, he who aids, abets and harbors an unregistered alien enemy becomes amenable to the Defense of the Realm Regulations.’”

“What was your answer?” The look of bewilderment was growing upon Brandon’s face.

“I made none. I was completely bowled out. But I went at once to see the mother. And this is where the oddest part of all comes in. After a little conversation with the mother, I discovered that she most sincerely believes that her son is—is a messiah.”

Again the stricken man closed his eyes.

“There we have the clue. In a very exalted way she told me how her son was born six months after her husband had been killed in action. She told me how she had prayed that all wars might cease, how an angel appeared to her with a promise that she would live to see the war which would end all wars; she told me how a son was born to her in fulfillment of the prophecy, and how she christened him John Emanuel. I was astounded. But now I have had time to think about the matter much is explained. The man is clearly suffering from illusions prenatally induced. There is no doubt a doctor would tell us that it explains his fits. It also accounts for his faith-healing nonsense. And there is no doubt that mother and son have reacted upon one another in such a way that they are now stark crazy.”

“And that is your deliberate opinion?”

“With the facts before me I can come to no other. It is the only charitable explanation. Otherwise I should have felt it to be my duty to institute a prosecution under the blasphemy laws. Only the other day there was a man—a tailor, I believe—imprisoned under the statute of Henry VII. But if, as there is now every reason to think, it is a simple case of insanity, one will be relieved from that disagreeable necessity.”

Brandon concurred.

“But as you will readily see, my dear Gervase, the alternative is almost equally distressing. To clear him of the charge of blasphemy it will be necessary to prove him insane; and in that event, of course, he cannot remain at large.”
