Cameron looked at him quickly.

There was no mistaking the entreaty in his face.
Mr.Rae spoke somewhat more hurriedly than his wont.

"If it is not asking too much, and if you can still spare time, your presence might be helpful, Mr.Dunn." "Stay if you can, old chap," said Cameron.

"I don't know what this thing is, but I'll do better if you're in the game, too." It was an appeal to his captain, and after that nothing on earth could have driven Dunn from his side.
At this point the door opened and the clerk announced, "Captain Cameron, Sir." Mr.Rae rose hastily.

"Tell him," he said quickly, "to wait--" He was too late.
