A mortise lockset incorporates an electrically actuated clutch within the lock case. The clutch selectively engages one latch operator to permit access through a door equipped with the lockset. The lockset further includes a key rotatable cam for retracting the latch. The lockset includes a lock bar that permits retraction of the latch by means external to the lockset. An extended throw deadbolt-like latch is held in a retracted position by an auxiliary latch and hook until released by retraction of the auxiliary latch. The latch incorporates a recessed roller in the projected end of the latch to facilitate latch deployment.
