time narcissist, just knows that his wife is having an affair with the dog trainer who lives upstairs in their luxury apartment building. But when he tries to catch them in the act, he finds the neighbor's corpse instead. And now he can't find his wife anywhere.

With only the building's alluring front desk person to help him, Paul must find the killer before the cops pin the murder on him. Soon, he discovers that his fellow over-privileged tenants aren't as bland as their jobs in digital marketing suggest, and he is drawn into a hidden world of greed, lust, and misused animal narcotics. But Paul's biggest obstacle to solving this mystery lies within himself. Can he stop lying, navel-gazing, and indulging in his own depression long enough to do some actual detective work? Or is the pool on the roof too damn enticing?

While serving up a who-done-it in the vein of Anthony Horowitz's Hawthorne and Horowitz series, Additional Attendee maintains the momentum and contains the grit of an Elmore Leonard novel. Along the way, it offers up a healthy dose of existential comedy in the tradition of Gary Shteyngart and Sam Lipsyte.
