Jerry had seen a man leave the public path, cross the Paddock, and enter the shed half an hour before.
"What kind of a man?" asked Silver.
"Trampy, sir," replied the lad.
"He got smokin' in it out of the wind," said Stanley, "and set it ablaze, and did a bolt."
"After shutting the door behind him with the colt inside," commented Silver.
He searched the grass on the outskirts of the shed for footmarks. Something glimmering in the dusk caught his eye. It was a wooden-handled sheath-knife.
Silver picked it up and showed it to the girl.
She said nothing.
"Billy Bluff!" called the young man. He shoved the knife under the dog's nose. "Sik him out!" he called. "Good dorg!"
Billy Bluff skirmished round and went off up the hill at score.
