A two-bolt lockset simultaneously locks and unlocks in response to a single action by an operator, such as a key and cylinder. A deadbolt couples to such an operator to project and lock or retract and unlock. A crank also responds to the locking of the deadbolt to move a slide that engages and locks an actuator of the second bolt, a latch bolt, to lock the latch bolt. The slide is biased away from the latch bolt so that upon retraction of the deadbolt and corresponding motion of the crank, the slide is freed of the crank and moves out of engagement with the actuator. Preferably, the slide is carried by a retractor so that both locks clear by the single turn of a single inside operator. The retractor responds to a retractor cam attached to the inside operator to translate. The slide moves out of engagement with the actuator upon such movement and forces the crank to withdraw the deadbolt.
