Your Sanity and You

Your Sanity and You is a book published in recent years by Dr. Philip Freedenberg. Its exact contents are unknown, but given the title, it seems to be intended as instructional material for agents who are concerned about the care and feeding of that elusive thing known as "sanity." No doubt it draws on Dr. Freedenberg's more educational experiences in his time as the Co-Director of the Department of Fictional Psychology.

Agent Supernumerary owns a copy.
