Let's say that X is a girl who has a deal with Y, she would absolutely get many benefits of that deal after it comes to its deadline. However, there's A, B, and C who are three people that hate X and want to destroy her deal with Y. X doesn't know about their planning until after a while, so she says:
"It was a _____ all that time!".
I thought of tri-scheme, but I'm not sure if it fits X's situation.
Any suggestion for a word that would describe X's situation?
Update:
1- I found "tri-aggression" and "tri-alliance".
2- I want a term as this one "tripartite aggression", but expressed with less violence.

There are a number of terms in English that relate to groups of three, none seem quite appropriate.
In your situation, X can say "It was that scheming trio all along!" or perhaps. "There was a trio of A, B and C obstructing me all the time". Changing "trio" to "troika" would suggest a rather more organised and conspiratorial group of three.
