“You may save yourself the trouble. They won’t be touched,” said the officer, decisively. “There has been too much stir about the last for the thieves to move again so soon.”

“I agree with you in that,” said Wilson. “They won’t be touched.”

“How about the investigation of your books?” asked Mr. Fitler. “Did you trace any loss?”

“Yes. There have evidently been robberies committed before. Three or four at least. Perhaps a dozen.”

“Ah! That is important. Running how long?”

“Over a year.”

“That changes the aspect of things. Have all your employes been with you that long?”

“All except Will.”

“That fact seems to clear Will. There will be no harm in watching him, though. I suppose you have received hundreds of invoices in that time?”

“Yes.”
