The Introvert by Michael Paul Michaud

A vacuum salesman by day, the introvert lives a quiet life alone with his dog until a work relationship and a dark secret from his past team up to create an uncomfortable imbalance in his otherwise ordered life, one that soon finds him squarely at the center of a murder investigation. With his thoughts continually urging him to make people “red and open” and to “achieve it” with his girlfriend Donna, what follows is a sometimes brutal, oftentimes hilarious, and absurdist account of the life of one very anti-social and unexpected anti-hero.
