You may signify your agreement to the terms of this letter by dropping a package containing the money and a signed statement to the effect that you will drop your pursuit of Baldy Turk and that you will not give evidence against our associates in the robbery case from the 5:15 express from Bayport next Thursday afternoon as it passes the grade crossing at the North Road."

"What on earth does it mean?" asked Mrs. Hardy.
Frank and Joe looked at one another in astonishment. Frank reached over for the letter and examined it. The strange document was typewritten on an ordinary quality of white paper.

"It must be a practical joke of some kind," said Mrs. Hardy, in perplexity.
"Practical joke, nothing!" scoffed Aunt Gertrude shrewdly. "Did Fenton Hardy go to Chicago after some criminal?"
"He went to arrest Baldy Turk," replied Frank.
"There!" Aunt Gertrude pounded the table.
