Covert actions are my daily life.
.العمليّات الخفيّة هي حياتي اليوميّة
Geheime Operationen mein täglich Brot.
Actuar en secreto es
mi pan de cada día.
Actuar en secreto es 
mi pan de cada día.
Mon quotidien était fait
d’activités secrètes.
Agire sotto copertura
 è la normalità, per me.
Ações secretas são
 minha vida diária.
Скрытность — моя обыденность.
