"You were watching with Darrell, then?" asked the Head.
"Certainly. We decided to see into this jolly business and catch the cad—er—the fellow that was doing it. Er—Clive and I were for duty to-night."
"Together?"
"No, sir. Separate. We were to meet every few minutes."
"You met then?"
"Often. At last Clive crept along and told me there was someone about. He asked me to watch at the far end of the corridor."
The Head nodded. Mr. Axim gave vent to a malicious chuckle.
"Well out of the way there, I think?" he asked. "Did you see anything of this chase which we are told followed?"
"What chase?" asked Masters, looking across at his friend. "I don't understand. I've been waiting there ever since in case Clive's man bolted. What's happened?"
There was an impressive silence for one whole minute.
