"At the tailor's, most likely. He is always talking about new clothes; but lately he hasn't had any because Merrill shut down on him on account of an unpaid bill."
"Then you had better see Merrill and ask him to take particular notice of any bills that Luke pays him."
"Innocence must often be suspected, or guilt would never be detected. It is the only way to get on the track of the missing bills."
Harry saw that this was reasonable and decided to call on Merrill the next day.
"Do you think Luke took it?" asked the tailor.
"I don't know. I don't like to suspect him."
"I haven't much opinion of Luke. He owes me a considerable bill."
"He prefers your clothes to Hayden's, and if he has the money, he will probably come here and spend some of it."
"Suppose he does, what do you want me to do?"
"To examine the bills he pays you, and if you find an ink spot on the center of one let me know."
