This has been just a joke until, at a crossroads marked by overwhelming marital and business stress, he actually encounters this Other Shulman-an incredibly successful man who's made life and career choices that Shulman has spurned.

At first, the Other Shulman is but a mere nuisance, a source of frustration brought about by mistaken identity. But as time goes by, his actions become increasingly destructive and threaten to sabotage all aspects of Shulman's existence.

The struggle between the two Shulmans comes to a head while Shulman is running in the New York City Marathon. And it is during the course of this race, as he runs through the old neighborhoods where his life took shape, that this ordinarily passive family man examines all the choices he's made and realizes that in order for him to get his life back on track he must confront and overcome his haunting demons as presented in the form of this angry doppelgänger, this Other Shulman.

In 26.2 chapters, one for each mile of the marathon, The Other Shulman is a hilarious and affecting tale of identity and aspiration from one of America's best-known comic writers.
