The boys saw both Wagner and Chester were provided with congenial situations. After the boys had been in Chicago a couple of weeks they met Katz and Cullen on Clark street. The detectives flamed red in the face at sight of the boys, but were very humble when addressing them.
"We have forgotten what took place in Wyoming," Katz said significantly.
"And so have we," replied Tommy. "No one here knows anything about it! It was rather a mean trick to play on you, but we had to do something to get Wagner to testify in the Fremont case."
"Forget it!" cried Katz, and the two went on their way, after receiving their badges from Tommy.
The boys had been in Chicago not more than a month when a letter from the famous criminal lawyer brought them to his office again.
"Are you boys ready to take a trip to the north?" he asked. "I want you to go way up into the Hudson Bay country and do a little work that a group of Boy Scouts can do better than any one else in the world."
"Sure, we'll go!" answered Will. "We were saying last night that we were getting tired of hanging around Chicago."
The boys started away the very next day. What they saw and did on the journey will be found in the next volume of this series entitled:
Boy Scouts in Northern Wilds; or, The Signal from the Hills.
