In the Light of What We Know

One September morning in 2008, an investment banker approaching forty, his career in collapse and his marriage unravelling, receives a surprise visitor at his home. He struggles to place the dishevelled figure carrying a backpack, until he recognises a friend from his student days, a brilliant man who disappeared years earlier, under mysterious circumstances. As the friends begin to talk, a journey begins that is by turns exhilarating, shocking, intimate and strange.
