A stymied reporter in his early thirties embarks on an investigation of three unconnected suicides. All he has to go on are photos of the faces of the dead. Other suicides begin to proliferate, while a colleague in the archives sends him historical justifications of self-murder by thinkers of all sorts: Diogenes, David Hume, Emile Durkheim, Margaret Mead. His investigation becomes an obsession, and he finds himself ever more attracted to its subject as it proceeds.
