When a safe house has been compromised, the procedure is very specific—a Changing of the Guard will be ordered. Every embassy employee holding a diplomatic passport will be summoned and everything in the house will be quickly carried away. Every secret hiding place in walls, floors and other nooks—called slicks—will be emptied of money, weapons, equipment and papers. Even dishes will be removed since they may contain fingerprints of recent occupants. At right, the case officer in charge watches his team carry the evidence away. Within an hour, nothing will remain. Nothing.
