"Could you be seen from the house?"
"I don't think so, the fog was very thick remember."
"Was any signal given?"
Bernard looked hard at his friend. "You think it was a trap?"
"I am certain. Was there any signal?"
"A peculiar kind of whistle. Something like this!"
Gore whistled in a kind of ascending scale shrilly and in a particularly high key. The effect on Conniston was strange. He jumped up from his seat and walked hurriedly to and fro.
"Judas," he said. "I remember when I was down here that the little scamp had a kind of whistle like that—something like it. Listen!" Conniston whistled also, and Bernard nodded.
"That's it," he declared; "the whistle was given twice."
"Then the boy was Judas. He used to signal to Victoria in that way when the pair were up to their pranks. Wait!" Conniston opened the door and whistled loudly in the same way. Twice he did this. Shortly after the second time the pattering of steps was heard and Victoria came running up the stairs with a lighted candle in her hand. She looked white and scared.
