A mortise lock includes a case. A locking slide forms a bore to receive a spring and a steel ball to allow the locking slide to be slidable with respect to the lock case to abut against and/or disengage from a locking latch. The mortise lock is operated by turning an inside knob to drive a deadbolt and a latch lever and the locking slide is moved inward to engage a lever hub assembly thereby ensuring a locked condition. The mortise lock cannot be unlocked by operating an outside lever. When an inside lever is depressed, the lever hub assembly is driven to cause the rocker arm to push away a hooking lever and a knob spindle assembly, thereby retracting the deadbolt and the latch bolt and simultaneously moving the locking slide outward to show an unlocked condition, whereby the mortise lock can be unlocked by operating the outside lever.
