A gripping play by an award-winning playwright, "Liar" examines the power and influence of human interaction and the perils of assumption. Mark is a young man who is anything you want him to be--a chameleon. He can be a friend, lover, thief, or confidante--but could he be a murderer? Jeremy meets Mark in a gay bar, and, shortly after, the two men end up on the roof of an office building where Jeremy mysteriously falls to his death. But did he jump, did he fall or was he pushed? After the "accident," Jeremy's estranged sister befriends Mark, hoping to establish a relationship with the person she assumes is her brother's lover. Effortlessly gaining her confidence, he insinuates himself into her life and her home. At first her husband resists Mark's charms, but soon he, too, is brought under the spell of the mysterious drifter. After knowing the brother only a matter of hours, Mark has charmed them all into telling him secrets they haven't even told each other, with shocking results.
