All his teeth showed, and his yellow eyes were glaring fiercely.
Julian, who had thrown a hasty and searching glance round the room when the light was turned on, sprang forward and bent down to him.
"Rip! Rip!" he said.

"Silly! What's the matter?
Silly dog!" and he began to stroke him.
Either this action of his, or something else not known by the young men, had an effect on the terrier, for he suddenly ceased barking, and began to snuffle eagerly, excitedly, at the bottom of the door.
"It's as if he were mad," said Julian, turning round.

"Hulloh, Val! What the devil's come to you ?" For he found Valentine standing up by the table with an expression of deep astonishment on his face.
He pointed in silence to the door.
"By Jove! that curtain again!" said Julian, with an accent of amazement.
"I'm damned!" The curtain was, in fact, drawn back from the door.

Valentine struck a match and put it to a candle.

Then he opened the door.
