“’Twixt seven and eight of the morning,” replied the Major.

“Quite so,” said Wyley.  “The incidents fit to a nicety.  Two years afterwards Ensign Knightley comes home.  He knows nothing of the duel, or any cause for a duel.  Lieutenant Scrope is still ‘Harry’ to him, and his best of friends.  It is all very clear.”

He gazed about him.  Perplexity sat on each face except one; that face was Scrope’s.

“I spoke to you all some half an hour since concerning the effects of a concussion.  I could not have hoped for so complete an example,” said Wyley.

Captain Tessin whistled; Major Shackleton bounced on to his feet.

“Then Knightley knows nothing,” cried Tessin in a gust of excitement.

“And never will know,” cried the Major.

“Except by hearsay,” sharply interposed Scrope.  “Gentlemen, you go too fast, Except by hearsay.  That, Mr. Wyley, was the phrase, I think.  By what spells, Major,” he asked with irony, “will you bind Tangier to silence when there’s scandal to be talked?  Let Knightley walk down to the water-gate to-morrow; I’ll warrant he’ll have heard the story a hundred times with a hundred new embellishments before he gets there.”

Major Shackleton resumed his seat moodily.

“And since that’s the truth, why, he had best hear the story nakedly from me.”

“From you?” exclaimed Tessin.  “Another duel, then.  Have you counted the cost?”

“Why, yes,” replied Scrope quietly.

“Two years of the bastinado,” said the Major.  “That was what he said.  He comes back to Tangier to find—­who knows?—­a worse torture here.  Knightley, Knightley, a good officer marked for promotion until that infernal night.  Scrope, I could turn moralist and curse you!”

Scrope dropped his head as though the words touched him.  But it was not long before he raised it again.

“You waste your pity, I think, Major,” he said coldly.  “I disagree with Mr. Wyley’s conclusions.  Knightley knows the truth of the matter very well.  For observe, he has made no mention of his wife.  He has been two years in slavery.  He escapes, and he asks for no news of his wife.  That is unlike any man, but most of all unlike Knightley.  He has his own ends to serve, no doubt, but he knows.”

The argument appeared cogent to Major Shackleton.

“To be sure, to be sure,” he said.  “I had not thought of that.”

Tessin looked across to Wyley.

“What do you say?”

“I am not convinced,” replied Wyley.  “Indeed, I was surprised that Knightley’s omission had not been remarked before.  When you first showed reserve in welcoming Knightley, I noticed that he became all at once timid, hesitating.  He seemed to be afraid.”

Major Shackleton admitted the Surgeon’s accuracy.  “Well, what then?”

“Well, I go back to what I said before Knightley appeared.  A man has lost so many hours.  The question, what he did during those hours, is one that may well appal any one.  Lieutenant Scrope doubted whether that question would trouble a man, and needed an instance.  I believe here is the instance.  I believe Knightley is afraid to ask any questions, and I believe his reason to be fear of how he lived during those lost hours.”
