Thomas Quincy is a middle-aged man who is a member of the US Army Reserve and works for the Reserves as a civilian too. He is lonely, so he coaxes an alley cat into the apartment where he lives in St. Louis, Missouri. He names the cat "PC." In this book, we see scenes from the life of PC, both in the neighborhood in St. Louis and in places in Ohio where Sergeant Quincy worked after he got a promotion. Wherever he went while he worked in the Reserves, God gave Mr. Quincy a good church home and people who supported him as a Christian. But this book is mainly about his cat. PC became Mr. Quincy's buddy.
