He was sober enough as he raised his head sharply and sprang to his feet.

In doing this the treacherous wig slipped still farther.

Before he could raise his hand to replace it Mr Armstrong had stepped forward and torn the mask from his face, disclosing the livid countenance of Mr Robert Ratman! The surprise on either side was at first beyond reach of words.

The miscreant stood staring in a dazed way, first at Armstrong, then at Roger, then at Gustav, who, being a Frenchman, was the first to come to his use of his tongue.

It is forbidden to sleep all night in the _salle a manger_." "Silence, Gustav! Go for a policeman," said Armstrong in a tone so strange that the faithful Gustav slunk away like a dog with his tail between his legs.
"Now, sir!" said the tutor as the door closed.
The wretch made one wild effort at escape.
