Its mind boggling but reminded me of Mughal time army which used to hire conspiracy scheme sensor and detector which were intelligent people. Since every kingdom were up against each other to protect the throne, their jobs were to roam around anywhere and deep smell if there is any conspiracy going on against them and catch the culprits and punish. By duty they were too devoted and diligent in their job that it created this idiom in Urdu which is still valid in today’s time:
“Sazishion ko har cheez mein sazish nazr aati hai”
