"I knew him by sight. Tall, fair-haired man; he was on the Bullingdon. I never met him, though. I didn't know many men at the House."

Barbara thought for a moment.

"I don't believe I know any one who was at Trinity in your time. Did you ever meet a man called Waring?"

"Jack Waring of New College? I've known him all my life. They're neighbours of ours in Hampshire. You know he's missing?"

Barbara nodded quickly.

"So I heard.… I suppose nothing definite's known?"

"I haven't met any of the family since the news was published, but I shall see his sister this week-end."

"Well, if you can find out anything without too much bother——"

"Oh, she's a great friend of mine," Eric explained. "It's no trouble."

Barbara turned to him with a rapid backward cast to her earlier quest.
