"Silver!"

"S-s-h!"

Silence, followed almost immediately by a gruff voice inquiring with simple directness what the dickens all this noise was about.

"Hullo!" said Kennedy. "Did you hear that? I wonder what's been up? Your brother was in it, whatever it was."

"Of course," said Jimmy Silver, "he would be. We can't find out about it now, though. I'll ask him tomorrow, if I remember. I shan't remember, of course. Good night."

"Good night."

Half an hour later, Kennedy, who had been ruminating over the incident in his usual painstaking way, reopened the debate.

"Who's Wren?" he asked.

"Wha'?" murmured Silver, sleepily.

"Who's Wren?" repeated Kennedy.
