Locked diary

A Locked diary is found by searching Sandy's desk in Brimhaven during the Returning Clarence miniquest after the Back to my Roots quest.

Selecting the option 'Unlock diary' turns it into an Unlocked diary. A player may fail to unlock the diary, and trigger a trap, resulting damage of possibly 907 life points. A higher Thieving level reduces the chances of this trap from triggering.
