Man in the Empty Suit

Life isn't easy for the time traveller who's seen it all. He's already toured the entirety of human history and the outside world. That's why this time traveller celebrates his birthday partying with himself. The year he turns 39, though, the party takes a stressful turn for the worse. Before he even makes it into the grand ballroom for a drink he encounters the body of his 40 year-old self, dead of a gunshot wound to the head. As he follows the clues, he discovers rampant paranoia and suspicion among his younger selves, and a frightening conspiracy among the elders.
