The Secret History1992
by Donna Tartt
Under the influence of their charismatic classics professor, a group of clever, eccentric misfits at an elite New England college discover a way of thinking and living that is a world away from the humdrum existence of their contemporaries. But when they go beyond the boundaries of normal morality they slip gradually from obsession to corruption and betrayal, and at last - inexorably - into evil.
