duplicitousness
Two-faced trait
Duplicitousness is the quality of being duplicitous—deceptive, two-faced, or deliberately misleading.
The word is an awkward formation, since duplicity already serves as the noun form of duplicitous: His duplicitousness was legendary works, but His duplicity was legendary says the same thing more elegantly.
Both describe someone who presents one face while harboring contrary intentions.
