Ben Sonnenberg grew up in the great house on Gramercy Park in New York City that his father, the inventor of modern public relations and the owner of a fine collection of art, built to celebrate his rise from the poverty of the Jewish Lower East Side to a life of riches and power. His son could have what he wanted, except perhaps what he wanted most: to get away.

Lost Property, a book of memoirs and confessions, is a tale of youthful riot and rebellion. Sonnenberg recounts his aesthetic, sexual, and political education, and a sometimes absurd flight into "anarchy and sabotage," in which he reports to both the CIA and East German intelligence during the Cold War and, cultivating a dandy's nonchalance, pursues a life of sexual adventure in 1960s London and New York. The cast of characters includes Orson Welles, Glenn Gould, and Sylvia Plath; among the subjects are marriage, children, infidelity, debt, divorce, literature, and multiple sclerosis.

The end is surprisingly happy.
