“You were glad enough to hush it all up when you thought it was young Wyndham had done it,” said Silk.

The captain winced, and Silk was quick enough to see it.

“You profess to be fair and honest. Do you call it fair to shelter one fellow because he’s your friend, and tell about another because he isn’t? Eh, Riddell?”

It was not a bad move on Silk’s part. The question thrust home, and had he been content to leave the matter there, it might have been some time before the captain, with his own scrupulous way of regarding things, would have detected its fallacies. But, not for the first time, Silk overdid it.

“Besides,” said he, seeing he had made an impression, and foolishly thinking to follow it up—“besides, young Wyndham’s a long way from being out of the wood himself yet. Of course I don’t want to do it, but I could make it rather awkward for him if I chose.”

The captain fired up scornfully, but Silk did not notice it, and continued, “You wouldn’t like to see him expelled, would you? If I were to tell all I know about him, he would be, to a certainty.”

Riddell, on whom these incautious words had acted with a result wholly different from what was intended, could scarcely contain himself to talk coolly as he replied, “Please leave my room. I don’t want you here.” Silk looked round in a startled way at the words, and his face changed colour.

“What?” he demanded. “Please leave my room,” replied the captain. “Not till you promise to get back the names.”

“I shall do nothing of the sort.”

“You won’t? You know the consequence?” Riddell said nothing. “I shall tell of Wyndham,” said Silk. “Please leave my room,” once more said the captain. Silk glared at him, and took a step forward as though he meant to try one last method for extorting the promise.
