"Besides, I'm dying to find out how the three little sociopaths got together in the first place. "
That one's easy. They all went to the same small college. Two of them were theater geeks.
Too easy. You haven't explained how they made the jump from theatre buddies to partners in crime, and what kept drawing back the one who transferred out (Cloyd).
I should say now that I was involved in theatre all through high school, and minored in it at college. And I went to a large college first and then transferred to a small one (an art school, smaller than this one), so I do understand some of the interpersonal dynamics.
Believe me, this has not been explained AT ALL to my satisfaction.
