“You probably are right,” Nick replied, with a nod. “One of the gang is known to have been wounded during their hurried get-away.”

“The man was Nordeck.”

“Undoubtedly.”

“That occurred a week ago,” Chick went on. “He evidently has been lying ill and in a bad way since then. There was convincing evidence of that. Furthermore, according to the neighbors we questioned, no physician was called and nothing definite is known about the couple. They have occupied the house nearly a month. They probably did not dare to call a physician, lest the wound might lead to an exposure of Nordeck’s identity and his part in the Westchester burglary.”

“That undoubtedly explains it,” Nick agreed. “Nordeck took a chance of recovery without the help of a surgeon. His negligence proved fatal. The writer of the letter must have been his daughter, Nancy Nordeck, whom I saw on a Harlem train a month ago.”

“That’s right, too,” Chick said. “The woman seen by the neighbors answers Nancy Nordeck’s description. She took care of her father till he died. Then she bolted, sending Chief Mallory that letter and a fifty-dollar bank note for funeral expenses.”

“It shows plainly enough that I was right.”

“In attributing the burglary to a gang including Nordeck?”

“Exactly. That bank note was part of the plunder,” said Nick. “Nordeck evidently got his share of it. He must have been dead broke before the burglary, however, or he would not have been living in such quarters as you describe. You searched the house, of course.”

“Every nook and corner.”
