FRED OFFERS TO SOLVE THE LOCKER MYSTERY For a week Gridley High School managed to get along without the presence of Fred Ripley.

That haughty young man was at home, nursing a pair of black eyes and his wrath.
Yet, in a whole week, a mean fellow who is rather clever can hatch a whole lot of mischief.

This Dick & Co., and some others, were presently to discover.
All outer wraps were left in the basement in locker rooms on which barred iron doors were locked.

In the boys' basement were lockers A and B.

Each locker was in charge of a monitor who carried the key to his own particular locker room.
As it happened Dick Prescott was at present monitor of Locker A.
If during school hours, one of the boys wanted to get his hat out of a locker the monitor of that locker went to the basement with him, unlocking the door, and locking it again after the desired article of apparel had been obtained.
Thus, in a general way, each monitor was responsible for the safety of hats, coats, umbrellas, overshoes, etc., that might have been left in the locker that was in his charge.
Wednesday, just after one o'clock one of the sophomore boys went hurriedly up the stairs, a worried look on his face.
