It was not long after that, when one of the most startling events in their lives occurred. This happened when they were detailed upon a Secret Service case. The adventures they met with were of the most thrilling description. Their lives were threatened by dangers, and they did some of the most marvellous work ever known in the department. But want of space here prohibits our giving the details in this story. We have reserved it for a new tale which will be issued in our next number. THE END. Read "THE BRADYS AND THE RUNAWAY BOYS; OR, SHADOWING THE CIRCUS SHARPERS," which will be the next number (80) of "Secret Service."
