"I am not so sure of that."
"What do you mean?"
"Nothing. I have an idea," answered the detective, who did not wish to tell the man how he now began to fancy that the factory for safety had been placed in the cellars. "By the way, did this man who was arrested give his name?"
"No. He refuses to answer any questions. He was, as you know, Mr. Jennings, arrested for trying to pass a bad shilling, but there is no doubt he fired the place. The bottle of petroleum he had in his possession was empty, and—"
"Yes! I heard all that. Where is he now?"
The inspector named a place near Rexton where the man had been incarcerated, pending being brought before the magistrate. "I am going that way," said the inspector. "If you like to come—"
"I'll come," said Jennings. "I intended to see this man. There has been a lot of talk about false coins being passed lately."
Mr. Twining nodded, and began to tell of various cases which had taken place in the district. The two took the train to the place where the police station to which the inspector belonged was situated. It was now after twelve o'clock, and Jennings thought he would have some luncheon before going to the station. But, unexpectedly, a constable seeing the inspector, came hurriedly towards him, saluting as he spoke.
"Please, sir, you're wanted at the station," he said. "A message was sent to Rexton."
"I have just come from Rexton. What is it?"
