A lever lock apparatus having a sliding bolt, a detent mechanism for locking the bolt against sliding movement and a plurality of levers. When using the appropriate key, the detent moves to allow the bolt to be slid to a locked or unlocked position. When the lock is under attack, and an inward force is applied to the bolt, the detent moves so as to maintain a detent fence away from the levers. Keeping or moving the fence away from the levers impairs the ability to pick or otherwise attack the lock.
